Char-Rumbler

The negative power is the joke and the warning both: a body that starts underwater, so the firebreathing isn't a luxury bolt-on, it's the engine that pays for the card existing at all. Double strike doubles every point you pump, which makes the math addictive: once you're above zero, each red you sink in is two damage on the swing, not one. But the toughness never moves, and the printed power begins below zero, so the creature does nothing until you commit mana on the turn you attack, leaving it a 3-toughness blocker that trades down against almost anything and dies to the smallest burn. The design is a deliberate tension between a payoff that scales explosively and a baseline that is, untouched, a liability. It belongs to the long line of red firebreathers running back to Shivan Dragon, but where those bodies carry their own clock, this one carries an anti-clock: you are spending mana to climb out of a hole before you can spend mana to win. That makes it a mana-sink finisher pretending to be a four-drop creature, reading as a trap to the curve-out player and as a combo enabler to anyone holding untapped red and a way to push it through. The whole risk-and-reward equation is front-loaded into a single subtracted point of power.
