Baralas, Lorebinder

Whenever you cast an instant or sorcery spell from
your hand, you may exile it with a Lore counter on
it instead of sending it to your graveyard.

Baralas gains prowess for each card in exile with a
Lore counter on it.

{t}: Until the end of turn, you may cast spells from
exile with Lore counters on them.
