Mortarion, Child Of Death

Flying, Menace
Creatures you control have Deathtouch and must
be blocked if able.
At the beginning of your end step, for each
opponent, if a creature that opponent controlled
died this turn, create a 2/2 black Astartes
Warrior creature token. Then, if you control 7 or
more creatures, each opponent loses life equal to
the number of creatures you control.
