Romina, Witch of the Arts

Ward—Discard a card.

Whenever you cast your first instant or sorcery spell
each turn, each opponent loses life equal to that
spell's mana value. You gain life equal to the life lost
this way.

{1}{u}{r}{b}, {t}: Instant and sorcery cards in your graveyard gain flashback until end of turn.
The flashback cost is equal to its mana cost.
