Attendant Of The Cinder Spirit

Haste, soul strike (Whenever you gain life for the
first time each turn, this creature deals 3 damage to
each opponent.)
Whenever Attendant Of The Sun Spirit or
another enchantment enters the battlefield
under your control, you may exile the top card
of your library. For as long as those cards remain
exiled, as long as you've gained life this turn, you
may play those cards.
