Hobgoblin, Mantled Marauder

A 1/2 that flies and swings the turn it lands is a curious frame for a payoff whose entire ceiling is set in the discard step. The trigger does the real work: each card you throw away pumps the power by two, and because it fires on any discard rather than a cast or an attack, it flips the usual downside of madness, cycling, rummaging, and hand-size clauses into a reward. That instant-speed pumping matters more than the printed body suggests. The bonus resolves whenever you discard, so a discard outlet fired mid-combat can widen the attack after blockers are declared, and the evasion pushes that damage over any ground defense (only a flyer or a reach creature can stand in the way). The counting is linear rather than exponential, so it rewards a deck built to shed several cards in a single window rather than one big pitch; how far it climbs depends entirely on how many discards you can chain before the turn ends. It is the reward half of a red discard package, a body that asks the rest of the deck to feed it fuel and then converts that fuel into flying damage.
