Colossal Titan

Colossal Titan enters the battlefield with twice
X +1/+1 counters on it.
As long as Colossal Titan has a +1/+1 counter
on it, it has reach, trample, and indestructible.
Whenever Colossal Titan enters the battlefield
or attacks, you may remove any number of
+1/+1 counters from it. If you do, Colossal
Titan deals that much damage to each other
creature and each planeswalker.
