Lava Zombie
A 4/3 for arrives with a string attached: the trigger bounces a black or red creature you already control, so the body costs you a turn of tempo and a re-cast unless the return is doing work. The design belongs to an era that paid for generous stats with mandatory enters-the-battlefield bounce, using the return as a brake on an otherwise undersized curve. The intended payoff is recursion of another comes-into-play effect: send back a Nekrataal-style removal body, a sacrifice creature, anything whose ETB you want to fire twice, and the bounce becomes engine fuel instead of lost board presence. The crucial point is that the return is not card disadvantage; you keep the creature, you just spend the mana and the turn to redeploy it. Pointed at a creature with no trigger worth repeating, the bounce is pure tempo surrendered, and the firebreathing clause (paying
for +1/+0) is a flood-relief mana sink that rewards a board already stalled rather than a remedy for the entry tax. What you get is a creature built for a deck that wants its own creatures back in hand, not one you slot onto a curve and forget. The body runs large precisely because the trigger is neither optional nor reliably upside; the rate is paid in the tempo you give back the turn it lands.
