Trickster's Elk
Bestow, on the older Auras, was a survival mechanism for the enchantment itself: attach to a creature for a premium, and if that creature dies the Aura stays put on the battlefield as a creature rather than heading to the graveyard with it. This one weaponizes that durability into removal. Cast for the bestow cost and the enchanted creature loses everything: all abilities gone, base power and toughness pinned flat to 3/3, every keyword and activated ability and triggered engine the target was built around wiped from its rules text. That is the real function, not a buff dressed as an Aura but an answer that neutralizes a threat by rewriting it while leaving a body behind. The design draws a hard line between a creature's stats and its text, and it charges only for the text: a commander that wins through its abilities becomes a vanilla 3/3, an indestructible finisher loses indestructibility, a graveyard looper loses its recursion. Because bestow makes this a targeted Aura spell, the permanent has to be a legal target to begin with, so it answers what it can reach rather than what protects itself. And the payoff is that green rarely gets clean text-denial like this, almost never with a fail-safe attached: if the enchanted creature dies, the Elk simply becomes unattached and stands up as a 3/3 of its own. You spend a removal spell and keep a threat on the board.
