Pendant of Prosperity

A shared artifact only works if the payout runs both ways, and this one hands the meter to an opponent while keeping the draw mutual. You choose which seat it enters under, so from the outset you are deciding who gets to spend the mana and pull the tap. Whoever activates it draws and drops a land first; then you, as owner, draw and drop a land in turn. The design belongs to a small class of political engines that trade raw advantage for table influence: you build a benefactor relationship with one seat, symmetrically advancing you both while the rest of the table falls a card behind each activation. The land drop is the quiet part that gives the artifact its real weight. It sidesteps the one-land-per-turn rule entirely, so a controller sitting on extra lands can ramp on someone else's clock, and the owner gets the same accelerated development for free. The catch is that you never touch it yourself unless you claw it back; its usefulness to you is entirely contingent on the opponent you gifted it choosing to fire it. That contingency is the point. It is a card built to open negotiations rather than close games, the kind of artifact that turns a durdle turn into a handshake and asks the table to decide who benefits from a favor nobody can quite refuse.
