Infinite +1/+1 counters on a creatureNear-infinite damage to creatures
How it works
Cast Blasphemous Act by paying at most 7, dealing 13 damage to each creature.
For each creature opponents control that is dealt excess damage, Fall of Cair Andros triggers, creating a 0/0 Army if you dont control one, and putting a number of +1/+1 counters on an Army you control equal to the excess damage.
