Flashback

Flashback is a keyword ability on instants and sorceries that allows the player to pay an alternative cost to cast the spell directly from their graveyard. The spell card is exiled when the spell leaves the stack. Flashback's equivalent for permanents is unearth.
==History==
The first tournament-legal cards with flashback were printed in Odyssey block, where a small headstone was marked next to the name, as an aid for remembering flashback spells in the graveyard. This was not repeated after that block. Non-mana flashback costs were printed in Torment, followed by off-color and unique other costs in Judgement. The mechanic returned in both the Time Spiral block and the Innistrad block. In Dark Ascension there were a cycle of spells that had a greater effect when cast from the graveyard. It also appeared in Modern Horizons, Commander 2019 and Modern Horizons 2.
During its return in Innistrad: Midnight Hunt, the first multicolor flashback cards were printed.
Starting with Phyrexia: All Will Be One, R&D have made Flashback a deciduous mechanic.
==Rules==
==Rulings==
*"Flashback [cost]" means "You may cast this card from your graveyard by paying [cost] rather than paying its mana cost" and "If the flashback cost was paid, exile this card instead of putting it anywhere else any time it would leave the stack." 
*You must still follow any timing restrictions, including those based on the card's type. You can only cast a sorcery using flashback when you could normally cast a sorcery. Likewise, when an instant (with flashback) is sent to the graveyard, that player may cast it from the graveyard once more during their opponent's turn.
*Casting a spell using flashback doesn't change the mana cost (or mana value) of the spell. You just pay the flashback cost instead.
*Effects that cause you to pay more or less when casting a spell will also affect what you pay when casting the spell using flashback.
*A spell cast using flashback will always be exiled afterward, whether it resolves, it's countered, or it leaves the stack in some other way.
*You can cast a spell using flashback even if it was somehow put into your graveyard without having been cast.
*If a card with flashback is put into your graveyard during your turn, you can cast it if it's legal to do so before any other player can take any actions.
