For each player to secretly choose the creatures, that player should write down their choices without showing them to anyone else. Each player then keeps their choices secret until all players simultaneously reveal their choices.

If a creature is chosen more than once, it is destroyed only once. For example, having a single shield counter on it would allow it to survive.
