Gloomfang Mauler

Backup on a seven-drop is an odd home for one of the mechanic's more forgiving deals. The keyword can shove its two counters and its granted evasion onto another creature, but the Nightmare pays no tax for the redirection: it stays a 5/5 with menace, so pointing the counters elsewhere adds seven power to the board across two bodies (a 5/5 and a beefed-up threat, both hard to chump) rather than trading one gain for another. When there is nothing else to target, Backup has nowhere to go but the source itself: the counters land on the Mauler, and it swings as a 7/7 with menace that a lone blocker cannot stop. The whole build is about refusing to be a stranded topdeck. Swampcycling is the escape hatch when the game wants land instead of a fatty, converting an uncastable bomb into fixing for two mana; the same slot flexes toward a body once the mana is already there. That flexibility is the design's real subject, because a seven-mana ground creature otherwise lives or dies on when it arrives. Menace keeps the payoff from being purely defensive: the counters want to be swinging, and menace makes a doubled-up board awkward to gum up with a single trade. It is a curve-topper written to survive the games where you never wanted a curve-topper, a more considered use of the cycling-plus-backup pairing than the mana value lets on.
