Zhalia, Coven Prodigy

Witches you control have +1/+1 and Hexproof.

Noncreature spells you cast cost {1} less to cast.

Pay {x} mana and exile a number noncreature spells from your graveyard equal to the amount of mana spent this way. Put +1/+1 counters on each Witch you control equal to the number of noncreature spells exiled this way. You can activate this ability at any time you could cast a sorcery, and only once per turn.
