Player-built lines, played out step by step — every beat, every memory swing.
Xros Heart is a swarm deck that puts several small Red/Blue Digimon on the board, then fuses them ("DigiXros") into a single huge Mega for almost no memory. This line stacks OmniShoutmon and friends, pays the DigiXros discounts to drop Shoutmon X7 nearly for free, deletes a blocker on the way in, and swings with bonus Security checks to crack the opponent open. It does not kill from an empty board — it wins by snowballing a wide board into one unanswerable attacker.
