Arwen's Gift

The interesting move here is the discount condition. Divination-plus-scry effects have been baseline blue card advantage for years, and the printed rate of four mana for scry 2 and draw two is deliberately soft: two cards deep with a light dig, nothing more. What the design does is attach a cost break to a board state the caster is already trying to reach, controlling two or more legendary creatures, and let that reduction turn a fair rate into an efficient one. The condition is checked on cast, so you are paying the reduced cost only when the game has already gone the way you want; it does not reward you for stumbling. That structure quietly steers deckbuilding toward legend density without demanding a tribe or a color pair: any deck stacking commanders, planeswalkers-as-creatures, or a cluster of unique bodies collects the discount as a side effect of doing what it already does. The scry 2 before the draw is the small optimization that separates it from a flat two-card refill, smoothing the top of the library ahead of the dig rather than after it. Read as pure design, this is a card-draw spell priced for the midgame that hands its best rate to the decks most likely to be ahead already, a reward layered on top of a board presence rather than a payoff you assemble on purpose.
