Crystal Colossus

Crystal Colossus enters the battlefield with four
+1/+1 counters on it.
If damage would be dealt to Crystal Colossus,
prevent that damage and remove that many
+1/+1 counters from it. For each counter
removed this way, create a colorless artifact token
named Crystal Shard with "{t}: Add one mana of
any color. Use this mana only to activate abilities
of nonland permanents you control.
