Mehrunes Dagon

Whenever a creature you control deals combat
damage to an opponent, create a 2/1 Dremora creature token with "This creature cannot block."
Whenever one or more creatures you control
deals combat damage to an opponent, you may
put a destruction counter on target permanent
that player controls and on target permanent you
control of the same card type.
When Mehrunes Dagon enters the battlefield,
destroy all permanents with destruction counters.
