Ballu, Hand of Extinction

{u}{u}{b}{b}: Bribe (Discard a card. Target opponent draws a card. That opponent sacrifices a creature and then sacrifices all creatures they control that share a creature type with the sacrificed creature.)
Whenever another creature you control would bribe a player, that player sacrifices a creature.
"I expected some sort of challenge. Instead, I find you sent a horde. Fun, yes. Challenge, no."
