Quinn Benet, the Synapse

Haste

Lightning Pain —You may play spells from your hand as though they had flash. As long as Quinn Benet, the Synapse is on the battlefield, instants and sorceries in your graveyard have flashback {x}, where
X is the spell's converted mana cost. You may also
pay life rather than mana to play these spells. For every 2 life paid, pays for {1}.
