Damage FTW!

This creature enters with three +1/+1 counters on it. Remove a +1/+1 counter from this creature: It deals 1 damage to any target.

If a source would deal damage to a permanent or player, it deals double that damage to that permanent or player instead.

Trample If damage would be dealt to another creature you control, prevent that damage. Put a +1/+1 counter on that creature for each 1 damage prevented this way. When Vigor is put into a graveyard from anywhere, shuffle it into its owner's library.
