The Dothraki Horde

The Dothraki Horde enters the battlefield with
four +1/+1 counters on it.
Whenever an opponent is dealt damage, you may
remove a +1/+1 counter from The Dothraki
Horde. If you do, create two 1/1 red Warrior
creature tokens.

as no khal has done before! I will kill the men in
iron suits and tear down their stone houses!"
