Eren, Rage Incarnate

Overwhelming Strength: Eren gets +2/-1 for each
+1/+1 counter on him.
Destructive Roar: Whenever Eren attacks, it deals
4 damage among any number of target creatures
and/or planeswalkers your opponents control
Titan's Resilience: If Eren, Rage Incarnate would
be destroyed, instead remove all +1/+1 from him
and transform him back to Eren Jaeger.
