Rally the Galadhrim

Conspire lets you pay for a duplicate copy of a spell with bodies instead of mana, and this is the clean expression of what that trade is worth: tap two creatures that share a color with the spell, and one clone becomes two. The interaction runs deeper than a doubling trick because of the reprioritization the copy gets. Conspire specifies that the extra copy may choose a new target, so the two tokens do not have to name the same creature. Point the base spell at your best value engine and the conspired copy at a second one, and a single card resolves two independent copy effects with two independently chosen subjects. The green-blue pairing is not incidental either: both colors supply the token bodies to pay conspire's cost and the creatures worth copying, so the mechanic's payment and its payoff live in the same shell. A developed board is the price of admission before the card does anything, which is what keeps a two-for-one clone at four mana from spiraling: you need creatures untapped to conspire, a target worth doubling, and the willingness to commit your board while it resolves. When those conditions align, the ceiling is high; when they do not, it is a fair copy spell at a fair rate.
