Djinn Illuminatus

Replicate as printed is a one-shot mana sink: pay the spell's mana cost again, on cast, to fork it into a copy. This Djinn rewrites that from a per-spell option into a standing rule, granting replicate to every instant and sorcery you cast at a cost equal to that spell's own mana cost. The result is a doubling engine that scales with your mana rather than your hand: pay the replicate cost once and a burn spell becomes two heads, a removal spell two targets, a draw spell two refills, and you can keep paying to fork as many times as your pool allows. The new-targets clause is where the reach lives, turning a single Lightning Helix into a spread of independently aimed copies the moment the extra mana is there. The 3/5 flying body is almost incidental; the seven-mana investment is buying the rule, not the creature, and the rule rewards a deck built on cheap, repeatable spell effects that gain more from being doubled than from being cast bigger. It lands squarely in Izzet's home territory, the game's enduring spells-matter pairing, and the two hybrid symbols that can each be paid as blue or red are the point made in miniature: a creature whose purpose is to make red's burn and blue's card-draw multiply off the same engine, whichever side of the pie you lean on.
