Glendower

As Glendower enters the battlefield, place one
time counter on him, remove time counter at the beginning of the next turn, when time counter is removed, create two 2/2 red devil creatures, they
have, "sacrifice this creature, target opponent
loses 2 life," this effect is negated if you take
combat damage or Glendower dies
"...These signs have mark'd me extraordinary;
And all the courses of my life do show
I am not in the roll of common men."
-Glendower
