SPELLSpell

Each time a Spell Card is activated, place 1 Spell Counter on this card when that Spell resolves. If a card with a Spell Counter(s) is destroyed, place its Spell Counters on this card. Once per turn, if you would activate a card effect by removing a Spell Counter(s) from your side of the field, you can remove that many Spell Counters from this card instead. If this card would be destroyed, you can remove 1 Spell Counter from this card instead.
