Soulpurger

When Soulpurger deals combat damage to a player, you may sacrifice it. If you do, each player chooses a card name and searches
another player's graveyard, hand, and library
for up to four cards with that name and exiles
them. Each player shuffles, then draws a card
for each card exiled from their hand this way.

I shall cleanse your heresy, at any cost.
