裁定
If you are instructed to return more creatures than you control, you must return all the creatures you control to their owner’s hand.
You may return this creature itself to its owner’s hand as its triggered ability resolves. If you don’t control enough other creatures, you must return it.
The ability doesn’t target any creature. You don’t choose what to return until the ability resolves. Once the ability has started to resolve, no one can respond to the choice.
