stage_effect

Puts a condition on a creature, or removes effects from it, to set up a test.

• apply: puts effect on the creature for seconds, as if from creator and ability when given.
• remove: removes the creature’s effects that match effect, ability and creator. With none of them given, removes all its effects.

The answer includes the creature’s effects afterwards, the creature and a cursor. The effects are the engine’s plain ones, applied the way the game’s scripts apply them.
