Flaring Flame-Kin

Strip away the enchantment and you have a vanilla 2/2 for three mana: the entire payload is conditional on something else doing the work first. That conditionality is the design knot. The body wants to be in an Auras deck, where it becomes a trampling 4/4 with a built-in firebreathing pump, scaling to whatever red mana you can spare in a single attack step. But Auras have always carried a structural tax: the moment your enchantment hits, you have committed two cards (the creature and the Aura) to a permanent that a single removal spell sends to the graveyard as a two-for-one. This card doubles down on that exposure by gutting itself the instant the Aura leaves, so the +2/+2, the trample, and the pump all evaporate together. It is built for a strategy that asks the player to accept fragility in exchange for a curve that snowballs, and it expresses that bargain more bluntly than most: with no Aura attached it does nothing remarkable, and with one it can punch through a stalled board in a turn. The firebreathing clause is the part that elevates the package, turning leftover mana into reach and giving the deck a way to close from a board position the raw stats would not suggest.
