Brawn, Amadeus Cho

Most card-draw payoffs ask you to spend your hand: cast the spells, empty out, cash in for damage or tokens. This inverts the tension. The power-up ability sizes the body to the cards you are still holding, so a full grip is not resources waiting to be deployed but fuel already loaded. The enters trigger refills you on arrival, and if you commit him the same turn he shows up, the cost drops by his own mana value, collapsing the activation to exactly so the discount and the payoff land together. The counters are permanent, which means the growth survives even after you empty out, but the once-only clause forces a genuine timing decision: cash in early for a modest bump while your hand is thin, or hold behind a stack of draw and detonate for a single enormous turn. That is the structural gap he fills. Blue-green card advantage has never lacked ways to draw; what it has lacked is a way to convert a fat hand into board presence without pitching it. Here the hand is spent by being kept, not played, and the finisher's size is a snapshot of exactly how much you have refused to let go.
