The hybrid mana in the cost is a feint. Three pips let you pay six generic, RRR, or any mix, so a mono-red deck can afford the body: but both abilities scale on how many colors you spend, not how much red. Cast it entirely off colorless mana and Converge gives it nothing, leaving a 2/2 whose anthem sits dormant. Pay in one color and it enters as a 3/3 with a single-color pump riding each spell. The ceiling belongs to a manabase stretched across three, four, or five colors, where Converge stacks counters up front (once, as it enters, and only then) and every instant or sorcery afterward swings the whole team's power by however many colors funded that spell. That anthem is a burst, not a foundation: a temporary +1/+0 until end of turn, so the payoff is alpha-strike arithmetic rather than a growing board. Trample makes the burst punch through chump blockers; reach lets the body cover the ground and the air. The design asks the same question twice, at two different moments. Converge answers it once at resolution: how many colors did you actually spend to cast it? The spell trigger re-asks it every cast after, rewarding a deck that is genuinely five colors when it matters rather than five colors on the mana screen. The red hybrid pips let the greedy build hide inside a cost a mono-color deck can pay, then pay out almost nothing if that deck actually shows up mono.
