Sizzling Changeling
Aggressive red usually pays for its beaters with a body that trades and then leaves you empty-handed, but this three-mana 3/2 turns the trade itself into card selection. The death trigger fires whether it chumps a blocker, eats a burn spell, or gets sacrificed for value, and it exiles a fresh card you can spend across a two-turn window. That timing is the interesting part: because the impulse-draw survives a full untap, a land you cannot afford this turn is still playable next turn, and an instant sits in exile waiting for the right moment. Red gets refueled off combat attrition, precisely the resource it burns through fastest. The Changeling tag does the rest of the lifting, dressing a three-power beater as a Goblin, an Elemental, a Warrior, or whatever a given tribal shell wants, and making every "when a creature of this type dies" trigger something it participates in. It is fodder built to be spent rather than protected: the death trigger is not a downside to work around but the entire reason to run it, and the more freely you throw the creature into the red zone the more it gives back.
