Temujin, the Counterforce

Defender, first strike, ward {2}

Whenever a spell or ability you control prevents noncombat damage that would be dealt by a source an opponent controls, Temujin deals that much damage to that opponent.

Whenever a tapped attacking creature an opponent controls becomes blocked by Temujin, that creature deals damage to itself equal to its power.

Temujin can block any number of creatures.
