Dragon Scales

Most combat Auras live in fear of a single removal spell: invest two mana wrapping up a creature, then watch both halves die to one trade. This one shrugs that off by attaching its comeback to the rest of the board instead of its own host. Every time a sufficiently large creature arrives, the Aura can crawl out of the graveyard and latch onto it, which turns a top-heavy creature curve into a renewable supply of attachment targets. It is an artifact of an era fixated on expensive creatures as their own reward, where casting a giant was supposed to trigger payoffs throughout your deck. The buff itself is modest and deliberately defensive: a small toughness bump plus vigilance lets a clumsy beater swing and still guard the ground. The rate was never the point; the engine is. And the engine is only as strong as the fatties feeding it. Surround this with two-drops and the return clause is inert text stapled to a weak combat enchantment. Surround it with a curve that keeps dropping behemoths, and it becomes a resource that punishes the opponent for killing your bodies, since each new colossus simply hands the Aura somewhere fresh to live. The threshold is the whole governor on the design: it asks for a specific kind of deck and gives nothing back to any other.
