Flame-Chain Mauler

The old firebreather's failing was always the chump block: pump the body all you like, a single wall of any size stops it dead and eats the mana you sank. This design welds menace onto the pump instead of relying on raw size. Each activation costs for +1/+0 and menace, so it works in two-mana bites rather than the classic single-red increment, but the payoff is evasion, not just reach. One blocker can no longer stand in front of it at all; the ground stall that neutralizes a plain firebreather becomes the exact board state where this creature forces damage through. That reframes the repeatable pump from a race tool into a way to break a clogged board, and the +1/+0 riding along keeps the threat from being purely nominal. The menace lasts only for the turn, which makes each pump an attack-step commitment rather than a permanent evasion grant, and that keeps the two-mana price honest against a defender who can afford to double-block once. On a 2/2 body it starts as a modest early beater and grows into a mana sink that scales with how much land you leave open: the kind of design that rewards flooding out, since every extra pair of lands is another point of pressure the defender has to answer with bodies it would rather be swinging with.
