Go Blank

Target player discards two cards. Then exile that player's graveyard.

The List

Strixhaven: School of Mages

If the target player has one card in hand as Go Blank resolves, they’ll discard it and the cards in their graveyard will be exiled. If their hand is empty, you’ll just exile the cards in their graveyard.
