Kampf oder Flucht

Teile zu Beginn jeder Kampfphase Deines Gegners alle Kreaturen, die er kontrolliert, auf zwei offene Stapel auf. Nur Kreaturen in dem Stapel, den Dein Gegner bestimmt, können in diesem Zug angreifen.

Pelear o Huir

Fuir ou combattre

Au début de la phase de combat de chacun de vos adversaires, séparez toutes les créatures que ce joueur contrôle en deux tas faces visibles. Seules les créatures dans le tas de son choix peuvent attaquer ce tour-ci.

Combatti o Scappa

闘争か逃亡か

Lutar ou Fugir

Fight or Flight

At the beginning of combat on each opponent's turn, separate all creatures that player controls into two piles. Only creatures in the pile of their choice can attack this turn.

Invasion

At the beginning of each opponent's combat phase, separate all creatures that player controls into two face-up piles. Only creatures in the pile of his or her choice may attack this turn.

Creatures which enter (or cards which become creatures) after the beginning of combat ability resolves are not placed in either pile. Since they weren't in the chosen pile, they won't be able to attack.

If you have two of these, then you will separate the creatures into piles twice, and the opponent will choose a pile each time. Only creatures that were in both of the chosen piles can attack.

The effect is best understood if you read it as "creatures not in the chosen pile can't attack."
