Water Tribe Rallier

A cheap white body whose real function only comes online once the board it helped build gets wide. The waterbend cost of reads as absurd on a 2/2, but the ability lets you tap your own creatures and artifacts to help pay, each covering a single generic mana, so the true price is a tax on a developed battlefield rather than a mana investment. That reframes a go-wide plan as card selection: the more permanents you have untapped, the cheaper the dig. The timing matters here, and it cuts against the aggressive instinct. Creatures tap when they attack, so they cannot also help pay for the ability that same turn unless they have vigilance; the natural window is on an off-turn, or with a board too clogged to swing profitably, where a stalled-out army becomes fuel for finding the next threat. The search itself is deliberately narrow, looking at the top four but pulling only a creature with power 3 or less, which keeps it from being a repeatable engine that digs up a haymaker. You refuel with more low-curve bodies, exactly the plan the ability was built to serve. This is a floor-raising piece for a token-and-Ally shell that wants its late-game draws to keep arriving as relevant creatures instead of dead lands, not a card that defines a ceiling.
