Narod, the Beige Flower
Combat math has been a fixed premise since the earliest sets: power is what a creature deals, full stop, and every pump spell and combat trick in the archive assumes it. This quietly repeals that premise for the whole table, swapping mana value in as the damage-assigning number for every creature at once. The consequences fan out in strange directions. A Grizzly Bears still swings for two, because a two-mana body maps cleanly onto two power, but that identity dissolves the moment you leave a curve where cost tracks stats. Cheap creatures with big bodies deal less than their frame suggests; expensive creatures cheated into play deal their full sticker price, because mana value is fixed at the printed cost and never shrinks (a reanimated eight-drop still hits for eight, no matter how it arrived). Token creatures with no mana cost deal nothing in combat, reduced to chump-blockers or evasive nuisances that can never actually close a game. The 0/5 frame folds back on itself: under its own rule this thing assigns three damage in combat despite showing zero power, all while daring the table to attack into a five-toughness wall that renders their own beaters mathematically incoherent. A symmetric rules-warp dressed as a throwaway three-color oddity, the kind of design that only functions because it rewrites an assumption no other card is built to question, and once it resolves, every attack step runs through arithmetic nobody rehearsed.
