An online card-battle game with real-time battle action, forcing players to pay attention throughout the battle. Players must select a Hero and build decks with a mix of Unit and Action cards to take advantage of their Hero's ability and defeat their opponents. The first player to eliminate the HP of the enemy wins.
In a world where various Capcom universes are intertwined, a mysterious woman has been going around leading heroes and villains alike to a place called the "Land of Illusion" for her unknown agenda.
Each player chooses a Hero and (depending on that Hero's level) can select one out of three Hero Arts for that Hero to use, which charges with the MP cost of every card they play in the match. Decks can be built with a maximum of 30 Cards, and up to 3 Elements (see below) can be used in the same deck. However, Decks containing 2 Elements can only hold cards up to 5 MP, and 3 Elements can only hold cards up to 3 MP. Players can build a deck with whatever Elements they wish, but building a single-Element deck with a different Element from that of the chosen Hero will count as containing 2 Elements by default.
There are two main types of cards:
As the name suggests, these are the characters from different Capcom universes that can be placed on the field (maximum of 3 per side at any time) with two main numbers: Attack power on top, and Health Points (HP) on the bottom. When a Unit's HP is reduced to 0, they are generally removed from the field and placed in the Graveyard, unless there are activated Abilities that say otherwise.
After the release of Adventures of a Tiny Hero, all Unit Cards are now categorized into one of six Tribes:
Two more Tribes were added under the "天都ノ國絵巻 The Tale of Amatsu no Kuni" expansion pack:
Some Units may be included in two Tribes at the same time, and be included in Actions that effect either Tribe.
Active abilities that can be played as long as the player has mana, sets off "Active Response" where each player has a chance to respond by playing an Action Card of their own (if they have the mana to do so) or simply Resolve the action. If multiple Action Cards are played in a chain, the Actions will resolve in reverse order.
Cards are split into four elements, which generally fall along these lines:
The following Heroes are currently playable in Teppen:
