Dismissive Pyromancer

Red looters come cheap, and most stop at the rummage; this one bolts a kill switch onto the body. The first ability is the familiar filter, paying a mana to dig past dead cards toward the gas and pitching fuel for graveyard payoffs or madness triggers along the way. What separates the design is the back half: when the looting is no longer worth a card, the creature converts itself into four damage aimed at a problem. That conversion is the whole tension. A 2/2 that taps to draw is a target the moment it lands, so the sacrifice ability turns an inevitable removal magnet into a planned exit, trading a body that has finished filtering for a removal spell that lands at four damage (enough to clear most midrange threats). The friction is that the tap gates both roles: you get one per turn from the same permanent, and committing to the kill ends the loot engine for good. It reads as a value creature with an off-ramp, but the more honest framing is a delayed removal spell that draws cards while it waits to be cast.
