Galadriel of Lothlórien

The clever part is the self-denial baked into the trigger: the scry 3 fires only if you handed the Ring to someone other than Galadriel, which means the card that most wants to be tempted also wants to keep the temptation off itself. That inverts the usual Ring-bearer payoff, most of which reward you for wearing the Ring on the creature that carries the text. Here the Elf Noble stands apart, feeding the engine from the sidelines while a lesser body takes on the Ring-bearer role and the escalating bonuses (and the attention) that come with it. The second ability is what turns the scry into a ramp-and-selection engine rather than a smoothing tool: every scry from any source becomes a chance to slam a land onto the battlefield tapped straight off the top, so the more you dig, the faster your mana grows. The two are meant to feed each other. Temptations you arrange elsewhere fire the scry 3, and the scry 3 then threatens to unbury lands, threading card selection, ramp, and the Ring subgame into a single value loop. It is a build-around that reframes who wears the Ring as a resource-management question rather than a combat one, which is an unusual axis for a three-mana creature to care about, and it means the Ring-bearer choice becomes a lever you pull for value rather than a body you protect.
