Heart-Piercer Manticore

A Fling stapled to a body, with the friction of needing a second creature on hand to pay for it. The enter trigger reads like a value bonus, but the sacrifice is mandatory in spirit if you want the damage: feed it a token, a soon-to-die attacker, or something whose death triggers you actually want, and the 4/3 redirects that creature's power at any target. That last clause is the part worth dwelling on. Most sacrifice-for-burn effects in red can only point at creatures or players; this one hits planeswalkers too, which turns a board of expendable bodies into a reusable removal engine when paired with anything that recurs creatures. The embalm clause is what makes the engine genuinely repeatable from one card: cast it, throw a creature for damage, let it die, then exile it from the graveyard for a second copy that triggers the sacrifice all over again. The token comes back as a white Zombie, color-shifted by the embalm mechanic, but it keeps the same 4/3 body and the same death-dealing trigger. The design lives at the intersection of aristocrats and burn: it wants a sacrifice fodder shell to feed it, and it rewards that shell with reach no other red four-drop of its era offered, then comes back to do it again after it dies.
