History Sandbox / TouhouLostBranchOfLegend

** The game has many cards that end the player's current turn and start another one. They are always subject to a UniquenessRule to make them harder to loop indefinitely, and they tend to come with other bonuses (e.g. dealing damage before the extra turn) and/or drawbacks (several make spells more expensive on the extra turn, one prevents you from drawing cards outside the initial draw step, and so on). TimeMaster Sakuya in particular has a good number of these cards, and she even a card with an effect that requires extra turns to trigger.

** The "Oil Painting" Shining Exhibit depicts Kaguya in the iconic pose Beatrice from VisualNovel/UminekoWhenTheyCry is painted in.

** All but one of the endgame bosses cleanse their debuffs every few turns, which makes stacking Poison or Lock On a lot more annoying. This is particularly painful for the [[LowTierLetdown Roukanken]] (the only Shining Exhibit that doesn't give ''any'' mana, instead making all your attacks apply Lock On), which didn't need yet another thing going against it.

* AntiFrustrationFeatures: Since there are colored mana, the game thankfully never rewards cards you cannot play. If a card costs a white and a blue and you don't have blue mana in your pool, it will never show up. This also means grabbing a Shining Exhibit that adds a new color opens up the ability to select new cards too!

** The mechanics of [[spoiler:Seija's Overdecorated Gold Cup]] are widely disliked: it ''takes away all your non-Shining Exhibits'' (except for the [[CameBackStrong Ultramarine Orb Elixir]]), and it can be pulled out as early as turn 1. Not only is it unfun to suddenly be denied a lot of otherwise fun Exhibits, but the mere existence of the Cup discourages you from even going for them in the first place -- you'll need a plan that can stand up to the TrueFinalBoss and doesn't require the Exhibits either way, so also making an Exhibit-based plan is kind of a waste of time.

No relation to ''VideoGame/TouhouLostWord'' other than being Touhou.

* TrueFinalBoss: [[spoiler Seija Kijin is behind the theft, and she's not going to be easily caught or taken down. She has hits hard multiple times, causes you to take damage when you play a card, and can only take 300 damage a turn. She also has Spell Cards which is basically her hauling out a powerful item to buff herself, including either slapping 3 Vulnerable, Weak or Frail on you, calling in flunkies every turn, or just plain outright getting rid of non-shining exhibits. Safe to say, she's the Heart analogue in this game. Oh, and that flunky thing and more are available at higher difficulties.]]

** Time Walk is an ExtraTurn spell that only costs 2 mana with no downside except for the strict rules that make it impossible to use it more than once a fight: even if you somehow get two of them (copying the card before using it, or just picking up a second one).

** A Soulgem from ''Anime/PuellaMagiMadokaMagica'' show up as an exhibit, with FlavourText about its danger:

* SpoilerInterface: Searching for cards in the Collection can hint at the names of unknown cards, such as [[spoiler:"Walk"]] returning [[spoiler:Time Walk and Walkman]].

*** The iconic Black Lotus, which provides three mana of any one colour, shows up an as an exhibit. While the exhibit's effect is not the same as the original, its FlavorText is something to the effect of "wouldn't it have been great if it gave three mana of any colour?"
** The card Sure Gamble is a nod to the similar card in ''TabletopGame/NetRunner''. Both cost 5 of a resource and give you 9 of it. Even the art is similar.
** Soul Gems from ''Anime/PuellaMagiMadokaMagica'' show up as an exhibit, with the FlavourText warning you to watch out if it gets cloudy.

---> '''Reimu:''' (You'd better stop staying up late.)

** Doremi can just end the run using her dream powers. On Lunatic difficulty, if she's in Dream Layer 2 and she manages to summon someone, the run is over.
** Events can kill the run as well, such as the "Insurance Fraud?" {{achievement|System}}:

* NonStandardGameOver: Doremi can just end the run using her dream powers. On Lunatic difficulty, if she's in Dream Layer 2 and she manages to summon someone, the run is over.

** The Bunbunmaru Newspaper is a DeckClogger that charges you 2 mana for removing it from your deck and unleashing a crappy attack that deals one measly damage to a random enemy. However, all enemies that give you this status also like to give themselves graze, each instance of which allows them to ignore one attack... and the Newspaper ''does'' waste a graze.
** Artificial Jewelry is a terrible Skill sold to you during the Yorigami sisters' event (tellingly, you have to pay ''more'' if you want to pass on it). It amounts to a DeckClogger, as all it does if you spend one mana on it is giving you a random mana (a mana of your choice if this junk card somehow gets upgraded). Even if you want to filter your mana, it's an extremely unreliable waste of a card slot. It has one use case: if you have the Exhibit that discounts Skills, it's a free mana in exchange for a card. ([[teal:Maths: I have to try taking it and see if, say, Sumireko wants to take it off the player's hands.]])

''Touhou: Lost Branch of Legend'' is a DeckbuildingGame heavily inspired by ''VideoGame/SlayTheSpire''.
