Treacherous Blessing
Enchantment
When this enchantment enters, draw three cards.
Whenever you cast a spell, you lose 1 life.
When this enchantment becomes the target of a spell or ability, sacrifice it.
Phenax is generous with gifts and unforgiving of debts.

If you cast a spell that targets Treacherous Blessing, you choose whether you lose 1 life before or after you sacrifice it. You lose 1 life even if you sacrifice it first.
