Bloodthirsty Adversary (extended Art)

Haste

When Bloodthirsty Adversary enters the battlefield, you may pay 2R any number of times. When you pay this cost one or more times, put that many +1/+1 counters on Bloodthirsty Adversary, then exile up to that many target instant and/or sorcery cards with mana value 3 or less from your graveyard and copy them. You may cast any number of the copies without paying their mana costs.
