Flashback

MTG Mechanic

You may cast a card with flashback from your graveyard. If you do, you pay its flashback cost rather than paying its mana cost. Flashback doesn't change when you can cast the spell, so a sorcery with flashback can still only be cast during your main phase. Also, casting a spell with flashback doesn't change its mana value. Mana value is always based on a spell's mana cost, even if you pay an alternative cost to cast it.
