Argothian Opportunist

Green ramp that pointedly refuses to do green's usual job: the Powerstone token this Scout leaves behind makes mana that cannot cast a nonartifact spell, which walls it off from most of what green wants to accelerate toward. No fat top-end creatures, no expensive sorceries, none of the reflexive ramp-into-bomb line. The mana lands in artifact territory instead, pointing you toward colorless costs, activated abilities, and construct-shell machinery. Powerstones exist precisely to distribute acceleration this way: a form of ramp that feeds artifact engines and mana sinks without also fast-forwarding every ramp deck's payoff. Bolting one onto a green body is a small act of color-pie negotiation. Green is good at generating tokens and bodies, so it gets to make the Powerstone; the mana simply refuses to speak green's language once it arrives. And it arrives a step behind, since the token comes in tapped, so the acceleration is deferred to the following turn. The package rewards a game plan with somewhere to spend colorless: artifact costs to pay, abilities to fire, something waiting on the mana rather than a green bomb hoping to be powered out early.
