Synchronized Charge

Green counter payoffs usually ask you to build around a single anthem or a single fat threat; harmonize lets this one fund its own second act off the board it just grew. The front half is deliberately modest: two counters split across a creature or two, then an immediate grant of vigilance and trample to everything you control that now carries a counter, including the creatures you just targeted. Nothing waits for a pre-built board; the spell primes its own payoff in a single resolution. The real design lives in the harmonize arithmetic. The graveyard cost starts steep, but the recast is discounted by an amount equal to the power of a creature you tap, so the very board you have grown pays down its own encore. That is where the counters do double duty: they make attackers bigger and they make the second casting cheaper, and a battlefield that never resets keeps compounding both. Trample turns accumulated counters into damage that survives chump-blocking rather than piling up harmlessly behind a wall. Vigilance keeps attackers untapped through combat, so the creatures you swing with are still available afterward to fund the next harmonize payment (the tapping happens as you cast the spell, so a creature spent that way is out of that turn's attack). Both casts pull on the same resource without cannibalizing it: the counters that power the front half are exactly what discounts and amplifies the back half, and a creature-heavy green board turns a modest sorcery into a two-stage engine.
