Stirring Hopesinger

Repartee reframes the targeted spell as something you cast on your own board as much as on the opponent's. The trigger cares only that an instant or sorcery has a creature in its crosshairs: point a heroic-style pump spell at your own attacker, aim removal at a blocker, throw a fight or ping spell across the table, and every creature you control grows in the same beat. That "each creature you control" clause is the payload, and it scales with the width of your board rather than the size of any single threat, which quietly turns this from a heroic enabler into an anthem engine that pays out per spell rather than per turn. The 1/3 flier with lifelink is doing custodial work here: it survives the early attrition that a go-wide deck fears, gains life off the same board it is pumping, and sits behind flying so it keeps ticking counters onto the team while dodging ground stalls. Targeted spells are usually one-for-one exchanges, and Repartee is the escape hatch: a deck built to cast many of them converts each pointed effect into permanent, cumulative advantage, so a spell already headed for the stack does double duty. The reward goes to a spellslinger shell that has learned to aim its interaction at its own creatures as readily as at the opponent's.
