SETUP — You are on the play: 3 memory, 5 cards in hand, empty board, 5 security each. In hand you need Dobermon and Plutomon, plus Cerberusmon: Werewolf Mode — the card you are about to throw away on purpose.
Place a card — Dobermon, cost 5 with 3 memory, so the counter crosses to their side. That is the price of setting the trap early.
On Play · When Digivolving — By trashing 1 card in your hand, delete 1 level 4 or lower Digimon.
Move a card from Hand to Trash — Werewolf Mode. Not a loss: Plutomon reanimates from there, so a card in the trash is a card already half-played.
Pass memory · end of turn — hand down to 3, their smallest body already gone.
They take the turn with 2 memory: draw, play a Digimon, keep a healthy grip. Their hand sits around 5 — and that number is what makes your next turn cheap.
