Bane of Progress

Naturalize on a stick was the easy version of this idea; clearing the whole board of both permanent types at once, and getting paid for it, is the version that asks something of you. Where green's single-target answers fire and forget, this folds the cleanup into a body that wipes every artifact and every enchantment in play simultaneously, your own mana rocks included, and grows fat off the wreckage. The +1/+1 counter clause turns a symmetrical sweeper into a payoff rather than a tax: the creature's size is a direct readout of how much you just destroyed, so the 2/2 base can land as a genuine threat against a board built on those permanent types. The symmetry is the discipline that stops it from being a free roll. It punishes the ramp deck leaning on its own rocks as readily as the artifact-and-enchantment value pile across the table, which puts the emphasis on timing: cast it when the asymmetry tilts your way, not the turn you happen to draw it. Six mana and a fragile frame mean it commits to the board the moment it matters and stays vulnerable afterward. But the destruction sits on the enters trigger, so blinking or recurring it converts a one-time wipe into a repeatable reset on two of the game's most resilient permanent types.
