Adeline, Resplendent Cathar
Most white aggro payoffs demand you already have a board before they do anything; this one is willing to build the board itself. The characteristic-defining power is the whole loop: it counts every creature you control, herself included, so her floor while alive is 1, and each token her attack trigger spawns raises the number she is built on. Crucially, that boost lands in the current combat, not a later one. Her power is a continuous effect that reads the battlefield constantly, and the tokens arrive during the Declare Attackers step, so by the time blockers go down she is already counting the bodies she just made. Vigilance is load-bearing rather than decorative: the tokens keep arriving every turn while she stays untapped to block, making a wide board the offense and the wall at once. What keeps the count honest is that it reads only the creatures actually present, so a board wipe collapses her back toward that floor, and the generator fires solely on your own attack step; she never manufactures bodies at instant speed or on an opponent's turn. Note the precise scope: she pumps only herself, never the tokens or the rest of the team, so the reward for going wide is her own escalating size rather than an anthem. Folding a per-opponent token engine and a self-scaling threat into one body is a tighter package than the go-wide archetype usually gets to run.
