Soulblade Djinn

The reward that gives spell-heavy blue decks a clock. Tempo and control builds have always struggled with the same closing problem: they fill a deck with cantrips, removal, and counters, then have nothing that ends the game. This Djinn turns every one of those noncreature spells into a combat boost, so the deck that was already casting six cards a game suddenly threatens to win off the back of all that interaction. The 4/3 flying body matters here: the anthem makes it a 5/4 the moment you cast anything on your own turn, and on a defensive turn the trigger fires off instant-speed spells to ambush an attacker or push a blocker out of range. The pump is the structural payoff, not the body. It rewards a reactive shell for doing exactly what it wanted to do anyway, which is the cleanest way to bolt an offensive plan onto a deck whose game plan is otherwise to say no. The 3-toughness back end is the honest cost: it dies to most of the burn and cheap red removal that aggressive decks lean on, so the Djinn wants to land into a board the controller has already stabilized rather than arrive early as a threat that demands an immediate answer. The anthem is conditional on your own spell density, too, so it does no work the turn you tap out for it, and the opponent gets a window to break the parity before you reload.
