Flashback

There is a tidy self-reference in naming an instant after the very keyword it hands out: this spell grants flashback to a card in your graveyard rather than being cast with the mechanic itself. The distinction matters for what it actually buys. For a single red mana, you recur any instant or sorcery in your yard at its printed mana cost, no discount, no timing change beyond the window this spell opens. That "flashback cost equals mana cost" clause carries the whole restriction. This is not a Snapcaster Mage effect that slashes the recast to a bargain; you still pay full freight for the spell you bring back, and the one red mana is the toll for the privilege. What it gives you in return is flexibility of target: any spell in the graveyard, chosen at instant speed, rather than one stapled to a body or locked behind a specific card. The design lives in the granted flashback's built-in exile. That exile is a rule of the flashback ability itself, not something written on the card you target, and it is what keeps this to a one-shot recursion of a spell rather than a loop. That single-use ceiling is what holds it back from feeding the kind of storm and burn engines that would gladly replay a whole graveyard's worth of copies. A red enabler for spell-heavy decks that want their best card back once, at the moment they choose it.
