OP

OP
The OP command is a Parenthesized Command that means the opponent does whatever is in the parentheses.

Basic Form
OP ( ---Effects---)

Detailed Explanation
OP can be used with several commands, but it is not correct in all situations.

If you're considering using OP, ask yourself, "Is this something I want the opponent to choose?"

MOVE Range:1 FROM Area:Hand, Side:Opponent TO Area:Grave


 * ^^^ You choose and discard 1 card from your opponent's hand.



OP (MOVE Range:1 FROM Area:Hand, Side:Player TO Area:Grave)


 * ^^^ Your opponent chooses and discards 1 card from their hand. Notice Side has changed, because the effect is now from the opponent's perspective.

Examples
