Origin of Metalbending

Green has always paid a premium to interact with artifacts and enchantments, and instant-speed destruction of either at two mana sits at the color's fair rate for that job. But the second mode reframes the whole card: a +1/+1 counter plus indestructible until end of turn turns what could have been a plain Naturalize into a combat trick that wins a block, blanks a targeted removal spell, or pushes a creature through a would-be lethal exchange. The counter stays after the turn ends, so even once the indestructible clause has done its protective work, the stat bump persists as a permanent upgrade. That permanence pushes the card past a fog-a-single-creature effect: you are not merely surviving the turn, you are ahead on board for the rest of the game. Being a Lesson ties it to a toolbox shell, where the flexibility earns its keep by letting one card cover both the noncreature-hate role and the protect-the-threat role without committing to either in advance. The cost is the modal choice itself: you pick one, and the mode you leave behind is the one your opponent was hoping you would need.
