Rowen, Lightning Duelist

Prowess
Whenever you cast an instant or sorcery spell,
Rowen, Lightning Duelist deals damage equal to
that card's mana value to target opponent.
Once each turn, you may cast an instant or
sorcery spell from your graveyard as if it had flashback.
"But people only die in proper duels, you know,
with real wizards."—Rowen, Lightning
