The instant-speed team pump at its most pared-down: one mana, +1/+0 across the board, no toughness, no evasion, no riders. Anthem effects that touch power alone live in a narrow band, and this one sits at the cheap, narrow end of it. Where a permanent like Glorious Anthem buys a lasting board-wide buff and Trumpet Blast adds extra reach for the same temporary effect, this trims the cost as far down as the wording allows and accepts the smallest possible payload. The whole calculus is in the instant timing: it is built to be held, then thrown after blockers are declared, so a wide swing that traded down on the math suddenly pushes lethal through, or an attacker that would have bounced off a blocker now connects for a point more. Because the buff is power only, it does not save your creatures in combat (a 2/2 trading with a 2/2 still dies); the payoff is offense, not survival. Its ceiling scales linearly with how wide you are, which means it does close to nothing on a thin board and a great deal on a flooded one. That is the trade-off baked into the rate: you pay almost nothing, and the card pays you back only in proportion to a battlefield you have already built. It is a finisher and a combat trick wearing the same coat, and which one it is depends entirely on the turn you cast it.
