Reckless Embermage

Most early pingers descend from Prodigal Sorcerer, the "tim" template that taps to deal one damage and asks for no mana at all, a structure that caps the effect at once per turn and leaves the body exposed. This rewrites that template with a different cost entirely. There is no tap and no per-turn limit, so buys as much damage as you can afford to pour into it, but every activation also strips a point off a 2/2 that survives only one ping of its own. The engine clocks itself: you can dome the opponent or clear small creatures as fast as your mana allows, with the math forcing you to count the embermage's own life total as a resource alongside red sources. The symmetrical self-damage is the brake on an otherwise untapped, no-ceiling burn outlet; it also flips into a feature when you want a creature in the graveyard or a death trigger off the embermage itself. The instinct behind it is older than the card: when an effect would be oppressive given away freely, charge for it out of the same body that produces it, rather than gating it behind a tap or a once-per-turn clause. The cost lives on the creature's toughness, which makes the player decide how hard to push before the engine consumes itself.
