The payoff lives in the graveyard, not on the battlefield. A 3/2 with trample for is a fine beater on curve, and trample is precisely the keyword that feeds the speed mechanic: excess combat damage spills through, chipping in the life loss that inches the speed counter upward. The loop is quietly self-reinforcing, since the creature applying the pressure is also the one advancing your speed toward the max-speed threshold that unlocks its second life. Reach that ceiling and the exile ability converts a dead card into a live one, paying
to draw. That structure rewards a shell that keeps attacking rather than stalling out, because the draw only comes online after you have been the aggressor, and each copy pays out exactly once. The design folds a mana sink and a sliver of card advantage into an aggressive body without asking the creature to do anything clever while alive; the reward is deferred until the board has already done its job. It is a tidy way to keep an early beater relevant deep into a game, when a naked 3/2 in hand would otherwise be the draw you least want to be holding on turn eight.
