Luck & Logic is a trading card game created by TCG company Bushiroad, the same company who makes Weiss Schwarz, Cardfight!! Vanguard, Tantei Opera Milky Holmes, and Love Live! School Idol Festival. It is part of "Project Luck & Logic", a multimedia collaboration franchise created by Bushiroad, which also involves a simultaneously-produced anime series, Luck & Logic, that serves as an introduction to the world of the game.
In the world of Septpia, interdimensional portals known as "Gates" have opened, leading to other, fantastical worlds not of our own. Within them exist beings dubbed Foreigners, extraterrestrial entities with enormous, otherworldly power, as well as access to the Paradox Zone, where the laws of nature do not apply and humans cannot exist. Their threat has resulted in the creation of an organization called the ALCA Parallel Dimension Opposition Agency. The members of ALCA are humans called "Logicalists", who ally themselves with friendly Foreigners that form Covenants with Logicalists to transcend limits with the power of Trance. When a Logicalist and Covenanter Trance, they combine to form a Tranceunion, a Logicalist/Foreigner fusion who can draw out the latent powers of the Foreigner and can access the Paradox Zone. By doing so, ALCA serves to protect Septpia from the dangers of so-called Dangerous Foreigners from other worlds.
Mechanically, the game plays like a mash-up of Weiss Schwarz and Cardfight!! Vanguard, inheriting rules from both previous titles to comprise the majority of Luck & Logic's ruleset. The goal of the game is to destroy your opponent's six Gates, which achieves victory. Players face off by Mobilizing Logicalists and Foreigners from their deck to partake in battle against enemy Logicalists and Foreigners and attack the Gates. By combining a Logicalist and a compatible Foreigner, the player can Mobilize an even stronger unit known as a Tranceunion, a combination of a Logicalist and a Foreigner that possesses the power to access Logic Drives with powerful effects.
Characters face off by comparing Power stats; the higher of the two comes out on top, and if the defender loses the fight, they are defeated and sent to Stock. Both players have the chance to fight back by utilizing the Logic Definition Phase, which enables them to play cards from deck and hand to beef up their character according to the character's Limit. In addition, the tides of battle can be changed with a Paradox Card, which changes the win condition for a single fight into the Aura stat, which is completely independent of Power and can help a weaker character overpower a much stronger one, potentially swaying the entire outcome of a duel.
The characters are divided into three categories: Logicalists, Foreigners, and Tranceunions. Each of these cards are also divided into Worlds representing the extradimensional realm that they originate from.
Unfortunately for the English players, Bushiroad announced that the English Edition was getting the axe a little over a year after debuting, with the March 2017 "Trance Re:union" set as the last English release and official shop tourneys running until the end of 2017, with a minor rules change enabling English cards to be used in non-Japan tourneys that use Japanese cards.
Judge your logic!
- A Form You Are Comfortable With: Foreigners shift appearance as the result of Septpia's Logic in order to appear natural to Septpia's residents. For example, pretty much all androids from Tritomy take the appearance of regular humans, and Aryol, a giant robot hawk, becomes just a giant hawk in Septpia.
- All There in the Manual: Several aspects shown in the Anime initially were left unexplained, however the Card Game fills in the blanks. The card game also adds additional info for former Covenanters the Protagonist allied with.
- Yosuchika had two Covenanters simultaneously while stationed in Hong Kong. Where they are however, is another story...
- Yosuchika was first partnered with Hibana of Disfia, having come to Septpia with other Disfia members to assist in the fight against Monolium Invaders. She was originally weary of partnering with him, as she was selected for him without his own input. After he dispelled her preconceived notions about him, the two became a great team.
- Rasetsu, also from Disfia, had wished to fight powerful opponents. Hearing of the Four Battle Kings of Monolium invading Septpia, he saw a great opportunity and went there. Due to Septpia's logic limiting him however, he Transjacked civilians so he could fight, prompting ALCA to send Yosuchika and Hibana. Because of Yosuchika bearing Disfia's emblem when Tranced with Hibana, Rasetsu refused to fight him, claiming he only fights those that are better than himself. They fought, but whereas Yosuchika fought seriously, Rasetsu merely toyed with him. Yosuchika however took advantage of the battle to learn Rasetsu's battle style and defeat him. Rasetsu expected Yosuchika to kill him, however Yosuchika merely captured him, refusing to take a life. He became Yosuchika's second Covenanter soon after, impressed by his courage and wishing to fight alongside the only one who defeated him. Both Yosuchika and Rasetsu were able to Covenant as they shared a great ideal, To never kill their opponents. Rasetsu willingly engaged in the Over Trance in order to save a Disfia foreigner caught in the crossfire.
- Like Yosuchika, Chloe simultaneously possessed two different Covenanter's before the series. While their locations are unknown, due to both being from Monolium, and the war with Monolium being over, both more than likely returned there.
- Chloe's first Covenanter was Daiga, a Fanged Beast from the world of Monolium stuck as a normal Tiger due to Septpia's Logic. He had come to Septpia while following the Four Battle Kings of Monolium, hoping to regain his lost honour after one defeated him in battle. After first arriving while in his Tiger form, whereas the public was in panic, Chloe rushed to the scene in order to make him her partner. Though he didn't want to use her, he agreed to be Chloe's Covenanter and help Septpia until he found the Four Battle Kings again. Worth noting is that it is implied because of Septpia's logic, Daiga was incapable of speaking unless tranced with Chloe.
- Chloe's second Covenanter was Fyrill, an Orca girl, and one of the best mermaids of Monolium. Drafted to be apart of the Four Battle King's Forces, Fyrill had no choice but to comply and Transjacked a civilian, only to be defeated by Naien's Logicalist's and captured. One day, Chloe went down to the prison on her day off looking for someone to talk too, and Fyrill became captivated by the Ribbon Chloe wore. The two talked every day about Septpia's fashion, with Fyrill now wishing to enjoy the fashion rather than fight for her clan. When a Monolium naval fleet attacked, Chloe and Daiga were placed on standby due to being ineffective in the water. Chloe however rushed to the prison and offered to free Fyrill in exchange for Covenanting. While Fyrill was grateful, she couldn't help but question why Chloe chose her.Chloe: I think we really get along!
- Like Yosuchika and Chloe, Tamaki possessed simultaneous Covenanter's. Unlike them however, she possessed three! While two are confirmed to be from Disfia, it is unknown where the third one originated. It is confirmed though that all three have returned to their worlds.
- Tamaki's first Covenanter was Xiaolin, Dragon Princess of Disfia, looking like a child due to Septpia's Logic. The Dragon Clan had sent Xiaolin from Disfia per tradition, so that she could gain the wisdom of parallel worlds, with her body changing to fit that which would most react to the new information. Though a Spoiled Brat at first, she and Tamaki bonded quickly over their roles as the Eldest Sibling of their family, becoming great partners.
- Tamaki's second known Covenanter was Kirin. Kirin is so far the one with the least information about it, only appearing in flashbacks in Episode 4 while tranced with Tamaki. Making matters worse is that unlike Tamaki's other Covenanter's, Kirin has no card form or lore, only having a passing mention in Venus' lore.
- The last of Tamaki's Covenanters was "Divine Music" Otohime. The youngest princess of the Mermaids inhabiting Disfia's Dragon Palace, she took advantage of the chaos caused by Monolium's war with Septpia to run away from home and go to Septpia, claiming to protect the Buddhist temples there. In actuality, while "Divine Music" Otohime was a great Biwa player, she was absolutely tone-deaf when it came to singing, and was ashamed that she was the only Mermaid like that. She resolved to flee to Septpia and only come back when she could truly sing, feeling she could only inherit the Dragon Palace if she could. While she played on the street, her Biwa captivated many, but drove them away when she sang. Tamaki was the only one who remained, having been shopping on her day off. When a Monolium Foreigner attack, Tamaki rushed her to safety, then fought against the Foreigner. Captivated by Tamaki's determination and passion to protect others, "Divine Music" Otohime began to play on her Biwa for several days in hope of cheering Tamaki one. One day though, she came to Alca and requested they covenant.That moment, the song the Foreigner presented was an otherworldly beautiful tune...
- Yosuchika had two Covenanters simultaneously while stationed in Hong Kong. Where they are however, is another story...
- Arc Welding: In some cards' flavor text, it is implied that the lore depicted in the cards is canon to that of the anime, and vice versa. For example, one of Olga's cards mentions being defeated by Yosuchika, which occurred towards the end of the anime.
- Badass Normal: Most Logicalists are otherwise normal humans, but in card game terms can go head to head with the mighty Foreigners.
- Boring, but Practical: Cards with higher-than-normal Power for its given Level tend to dispense with card effects and focus on crushing opposition with brute strength.
- But Thou Must!: Unless you buy the cards individually, buy a ton of boxes, get promos, or simply get the cards from someone else, it is impossible for one to play the game without buying a Starter/Trial Deck first. This is because the Starter and Trial Decks are packed with a set of ten Gate Cards, which are required to even play the game. This is possibly the only card game that requires this.
- Cat Girl: Aisha.
- Child Prodigy: Nina Alexandrova. 10 years old, college-level intellect.
- Color-Coded for Your Convenience: Cards are color-coded based on primary strengths, similar to Weiss cards. Red specializes in overwhelming power, Yellow specializes in defense and support, Green specializes in Stock power, and Blue specializes in deck power and Limit boosting. Unlike Weiss, color isn't nearly as significant to gameplay, and only serves to differentiate card styles. The one exception is attempting to Mobilize a Tranceunion from your hand without Trance, which requires a card of the same color on the field.
- Cute Bruiser: A lot of the girls.
- Deader than Dead: After a refresh, the top card of the shuffled deck is banished. This card can in no way be interacted with whatsoever.
- Discard and Draw:
- You can pay 3 Stock to draw a card. This is called a Luck Drive.
- Disfia cards tend to force the player to dump cards into the Drop Zone, which prevents you from playing them normally. However, Disfia's specialty is playing from the Drop Zone.
- Dub Name Change: The official lore packaged with the Trial Decks changes the "Another Logic Counter Agency" into "ALCA Parallel Dimension Opposition Agency", the latter in which the term "ALCA" no longer has a meaning. Contrast this with the Funimation subs for the anime, in which ALCA retains its proper name.
- Equippable Ally: Covenanters that Trance with their Logicalists basically become battle gear and costumes in their Tranceunion state. They tend to not cover a whole lot, for some reason.
- Fusion Dance: Tranceunions are this between a Logicalist and a Foreigner. In-game, this means that if you overlay a Logicalist and Foreigner, you can Mobilize a Tranceunion from your deck that gains a power boost from its overlay cards (known thereon as "Soul") and access to Logic Drive. You can still play Tranceunions from hand without Trancing, but Tranceunions Mobilized this way do not have Soul and therefore do not gain the extra Power or Logic Drive.
- Heroic Sacrifice: Many low-level cards have the "Intercept" ability, denoted by the "IC" marking. If another Member on your side of the field is attacked by an opposing Member, you can expend a card on the field with Intercept to have the defender gain Power without consuming Limit.
- Highly-Visible Ninja: Mana and Mei's Tranceunion. Her "outfit" is little more than a bra and short shorts.
- Mei herself somewhat qualifies as well.
- Hoist by His Own Petard: The Level Boost rule requires you to play a card if you use it, no exceptions. The problem arises when you've already played a Paradox, and you use Level Boost and wind up drawing a Paradox. In this case, if the card acquired via Level Boost is the only card in your hand, you are forced to play it, which means you just canceled your own Paradox. If you were intending on winning a fight via Aura, this can really mess with your day.
- Hospital Hottie: Tamaki and Cure's Tranceunion.
- Hotter and Sexier: Than Vanguard or Buddyfight. A good chunk of cards are humanoid girls/women, and a good chunk of Tranceunions involve Logicalists wearing Stripperific battle armor made of their Foreigners.
- Humongous Mecha: Sigma.
- Luck-Based Mission: As with all card games, but Luck & Logic makes an attempt to downplay this as much as it can, since the title is "Luck & Logic", as it tries to play up the usage of actual tactics instead of pure RNG.
- Luck Manipulation Mechanic: Cards from Tritomy specialize in changing the order of the top cards of your deck, allowing you to influence the outcome of cards that call for playing a card from the top of your deck, which there are many of in Tritomy.
- Mana Meter: Stock, which is used to pay for card effects, and is gained at the start of every turn, through abilities, or when one of your characters dies. Unlike other Bushiroad games, Stock isn't used nearly as much due to a large majority of characters having 0 Cost, which has the effect of causing Stock to pile up to rather high numbers over the course of the game. Stock does have an additional effect in this game, in that you can expend 3 Stock to draw a card; useful if you're lacking hand advantage.
- Mr. Fanservice: Pretty much all of the guys.
- Ms. Fanservice: Oh man, where do we start. Venus, Artemis, Athena, Enki, Melchi, Lucia, Aisha, 75% of the female Tranceunions...
- More Dakka: Tamaki and Sigma's Tranceunion is essentially 90% weapons. All of which are either auto-fire guns or rockets and missiles.
- No-Sell: You can cancel a Paradox with a Paradox of your own. This negates the Aura Battle rule, but does not remove any Continuous effects applied by the cards themselves. Some cards can even use their effects to negate Paradoxes without the use of a Paradox.
- Red and Black and Evil All Over: Lucifer.
- Shock and Awe: When Salt and Yukari Trance, the resulting Tranceunion is often depicted with lightning powers.
- Stripperific: So many Tranceunions. If the Logicalist is female, the resulting Tranceunion will almost always be this. Even the ones that aren't this tend to be pretty sexy anyways, like Ashley Tranceunions.
- Team Mom: Yukari is portrayed as this.
- Three Laws of Robotics: A card called "Three Laws of Robotics" exists. Salt also references it in flavor text on the card "Battle Agent, Salt".
- Wholesome Crossdresser: Ginei.
- Weak, but Skilled: Cards with the "Vanguard" ability. They tend to have pitifully low Power ratings, but as long as the opponent has no broken Gates, they have the power to immediately dispatch a Level 1 unit on the opponent's front row via discarding themselves when played.
- Wutai: Disfia is oriental-themed.
