Kir, Ender of Dark Plans

First strike
As you cast Kir, target player reveals their hand.
Choose a nonland card from it. Silence that card.
(Exile that card. Spells with the same name as the
exiled card can't be cast for as long as that card
remains exiled.)
Kir's power is equal to the total converted mana
cost of silenced cards opponents own.
