집중마법
0에서 13사이의 수 한 개를 선택한다. 각 플레이어는 그 수만큼 생물을 희생한다.
If a player controls fewer than the chosen number of creatures, they will sacrifice all their creatures.
Starting with the player whose turn it is, each player in turn order chooses which creatures they will sacrifice, then all the creatures chosen by all players are sacrificed at the same time. Players get to know the choices made by players who chose before them.
The numbers you may choose include 0 and 13.
