Songcrafter Mage

Flashback rebuilt from the outside. Rather than stapling a recast clause onto a spell before it enters the graveyard, this hands harmonize to a card already sitting there, and harmonize is flashback's flexible cousin: you tap creatures to shave the cost by their power before paying the rest. The two ideas fold together cleanly. Flash means the enter trigger can fire on the opponent's turn, so the instant or sorcery you rebuy is cast at whatever timing that spell allows, and the creature that just flashed in is itself a body you can tap toward the discount. The harmonize cost equals the target's printed mana cost, colored pips and all, which keeps the recursion honest: you are not cheating the cost, you are paying it in full minus whatever board presence you are willing to commit, then exiling the card rather than looping it. That exile clause is the ceiling. Each trigger is a one-shot rebuy, so the value lives in picking the right card in the yard and converting standing power into a discount, not in an engine that grinds the same spell forever. As a three-color Bard, it wants a deck already leaning on cheap creatures and a graveyard full of spent burn and cantrips, where the 3/2 frame is enough to pressure the game the turn it arrives.
