Rules and Ambiguities

General Rules

Game Phases

Active Phase: unsuspend (unrest, make active) all your cards that are in suspended (rested) state.
Draw Phase: draw one card from your deck to your hand.
  • If a player cannot draw because their deck is empty, that player loses.
  • The player who goes first does not draw a card during the draw phase on their first turn.
Nursery Phase: players do one of the following.
  • Hatch a Digi-Egg:
    • Draw one card from the top of the Digi-Egg deck, and place it face up in the Nursery Area.
    • Can only be done when there are no Digimon in the Nursery Area.
  • Move a Digimon from Nursery:
    • A Digimon can be moved from the Nursery Area to the Battle Area once they have reached level 3 or higher (Digimon below level 3 cannot enter the Battle Area).
    • Moving Digimon from the Nursery Area to the Battle Area is not considered Summoning, so Summoning Effects are not activated
    • It is possible for a Digimon to perform an attack on the same turn they were moved to the Battle Area.
  • Do nothing
    • Do nothing and proceed to the next phase.
Main Phase: the primary phase of the game, players can perform as many of the following actions as possible, in any order.
  • Playing (summoning) a digimon.
  • Digivolving a digimon.
  • Playing (summoning) a tamer.
  • Playing an option card.
  • Attacking with your digimon.
End of Turn: if the memory goes to 1 or above on the opponent’s side due to costs or other effects, the turn ends, and it becomes the opponent’s turn.

Tamer Cards

  • There is no limit to how many tamer cards can be played in a game.
  • Tamer cards cannot become targets of a digimon's attack.
  • Tamer cards at suspended/rested state can still trigger their main effects (unless specified).
    For example: A [ST1-12] T.K. that is suspended/rested due to [BT2-041] ShineGreymon's effect will continue to buff security digimons. See #37 of FUN Digica (at minute 16:42).
