Inferno Hellion

A 7/3 trampler for four mana is an aggressive rate by any era's math, and the shuffle clause is what pays for it. The deal is blunt: swing once, hit for seven through chump blockers, and at end of turn the body goes back into your library, leaving nothing for an opponent to kill on the crackback and nothing for you to redeploy. It is a one-shot delivered by a permanent, structured as a creature so it can sit on the battlefield untouched until you choose the turn to throw it. That timing window is the whole gamble: the shuffle only fires if it attacked or blocked, so a Hellion that stays home stays put, and the trigger checks at each end step rather than yours, meaning you cannot block with it on a defensive turn and keep it either. The 3 toughness is almost decorative; you are never meant to trade with it, only to send it. As a piece of red design this is the rental archetype in creature form, closer to a burn spell with legs than a board presence, and the shuffle that looks like a downside is really the safety valve that lets the power level run this high without giving the attacker a repeatable threat. You get the alpha strike or nothing.
