The manga series based on Culdcept, a card-based videogame. The manga was drawn by Shinya Kaneko and serialized in Japan by Kodansha in Magazine Z, and collected in six bound volumes. It is licensed in English by Tokyopop, and in Indonesia by Elex Media Komputindo.The manga revolves around the adventures of Najaran, a Cepter (card-user) under the tutelage of master Cepter Horrowitz. With her worrywart companion, the sentient staff Goligan, she embarks on a journey save the Culdcept (the book which the goddess Culdra had kept all the cards in until the War of the Gods) from the Dark Cepters.
One of the minor characters in the Cepter's Guild mini-arc has a card named Colossus.
The Berserker: Zeneth does not distinguish much between foe and collateral. It is shown later that his battle strategy is basically throw as many destructive creatures and spells to his adversary. One of his creature cards is even named Berserker.
Berserk Button: Najaran does not like a cepter who mistreats or takes his/her summoned monsters for granted. Chimino found this out the hard way.
Big Eater: Najaran can eat most anything, in large quantities.
This becomes a bit of a Chekhov's Skilltwice in the Bistym Forest arc, in which she ate a veritable forest of shrooms in the first trial and then determined the right dryad to capture on the second trial based on her self-taught skill of distinguishing good veggies from the bad.
Fantasy Kitchen Sink: Justified. Culdcept is the book in which Culdra inscribes the knowledge of the past, present and the future. In the War of The Gods, it was shattered by Culdra to stop Baltheas... taking with it the inscribed knowledge Culdra meant for the future. Pieces of Culdcept fell down to earth and becomes the cards, and they get experimented upon by alchemists, who in turn reverse-engineered the knowledge of the future to be built in more mundane means.
Fight Like A Card Player: Averted. Cepters do fight with cards, but the majority of people (including some Cepters) fight just as capably with more mundane means.
Five-Man Band: In the Bistym Forest arc, Najaran is part of such a group.
Nice Job Breaking It, Hero: In the Bistym Forest arc, Zeneth destroyed Old Willow with his tank, thus letting loose King of Ground Dark Master.
No Ending / Left Hanging: the manga stops at the point when the baddies obtain Endaness (returned into card form) and Flame Lord (by cutting off Zeneth's arm). It's presumably never finished.
Oh Crap: Glubell's scrying on the Migoals' headquarters, revealing that there are more than one Wind and Earth King. Meaning, those hard-as-nails-to-beat monsters are merely Elite Mooks.
Old Master: Horrowitz and Salvathor both are quite old when they start tutoring Najaran and Zeneth, respectively.
The Omniscient: Glubell is borderline this. She can 'read' the destiny (past, present, future) of an object or creature. Naturally, she can't read Najaran (and possibly Goligan, too).
Our Elves Are Different: Kigi's ilk. For one, they can turn into Dark Elves if the forest of Bistym gets tainted by human greed or otherwisely compromised; they get stronger, but they can't control their power.
A bit of a subversion too, because not everyone who had a pointy ear is an elf in this story.
Power Trio: Glubell, Horrowitz, and Salvathor (Zeneth's teacher) were once allied, of the Two Guys and a Girl variety. Cepter alliances like that are exceedingly rare; it is said that eventually greed will broke alliances between Cepters.
Red Baron: "Southern Tiger" Ouen. Many of the cepters in Cepters' Guild has nicknames too.
Tsundere: Tesla, a minor character. Kigi also shows shades of this.
Turned Against Their Masters: This is what Goligan said would happen to summoned monsters if a Cepter cast spells exceeding his/her power capacity.
Endaness, in a sense. All of the other Dagons had died out due to infighting, and she is the only one left. She had also mellowed out from her kin's evil and destructive tendencies, although arguably still within Chaotic Neutral territory.
Turtle Island: The Cepter's Guild stands on this. It's actually on the back of Endaness's massive true body. Justified that Endaness never dove since the inception of the island; not that she can't.
Vancian Magic: Arguably, the cards. Cepters arrange them into Books (in-universe terminology for a deck) about the same way you would expect a Dungeons & Dragons wizard would prepare their spells for the day.
Subverted in that Cepters still need to power the cards with their own powers, although the cards do form 'packets' of magic and is mostly stackable.
