Deck: exactly 1 Leader and 50 Characters, max 4 copies per name, every Character matching the Leader's color.
Chakra (5) and Summon (1) are fixed for both players and are never deckbuilt.
Each player draws 5 opening cards; only the player going second may take a mulligan.
A turn runs Draw, Main, Attack and End. The starting player draws 1 on their first turn and 2 afterwards.
During Main you may summon up to 1 Character for free and set any number of face-down Support cards.
Recovery: from your second turn, tap your Leader to flip every spent Chakra back face-up at once.
EX Characters cannot use the free Summon - they need the Summon Requirement printed on the card.
No attacks are allowed on either player's first turn, and a Character cannot attack the turn it enters unless it has Rush.
Only tapped Characters can be attacked. The opposing Leader can always be attacked directly.
Character combat compares the attacker's Power with the defender's remaining HP: meet or beat it and the defender is K.O.'d, otherwise the damage stays on the card.
A direct attack on the Leader applies the attacker's Damage stat to that Leader's Life.
Summoning, activating an Activate: Main ability and declaring an attack each open a priority window.
The player who opened a window never acts first in it; the other side responds or passes, and priority keeps alternating.
Queued activations resolve in reverse order, so a later response can negate the one before it.
The match ends the moment a Leader's Life reaches 0.
