{2}, {T}, Exile The Stone Brain: Choose a card name. Search target opponent's graveyard, hand, and library for up to four cards with that name and exile them. That player shuffles, then draws a card for each card exiled from their hand this way. Activate only as a sorcery.
The ability has no effect on permanents with the chosen name that are on the battlefield.
Unlike most effects of this kind, The Stone Brain's ability allows its controller to choose the name of a basic land. Note that you may only search for up to four copies of that card, even if you find more of them.
You don't have to choose the name of a card that you've already seen this game; you may guess at a card you think your opponent might have in their deck, if you'd like.
You don't have to exile each card you find with that name. If you want to leave one in their graveyard, for example, you may.
You target a player as The Stone Brain's activated ability is put on the stack, but you don't name a card until it resolves. Notably, this means that players don't get to respond to the ability knowing what card you will name.
