Karazikar, the Eye Tyrant (Extended) [Dungeons & Dragons: Adventures in the Forgotten Realms Commander]

Whenever you attack a player, tap target creature that player controls and goad it. (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.)

Whenever an opponent attacks another one of your opponents, you and the attacking player each draw a card and lose 1 life.
