Dihada, Binder of Wills

Mardu had lacked a planeswalker built to helm a legends deck, and the design here answers that gap with unusual precision, folding protection, selection, and finish into a single loyalty track that only works when the deck is stuffed with legendary permanents. The whole card runs on that assumption. The +2 hands a single legendary body vigilance, lifelink, and indestructible until your next turn, which is exactly the insurance a legends deck needs for the one piece it cannot afford to lose. The −3 turns the same legends-heavy list into repeatable card advantage: it digs four deep, keeps the legendary cards, and consoles you for the misses by dropping them into the graveyard and minting a Treasure for each, so a whiff still ramps you toward the next recast rather than leaving you empty-handed. Both abilities point the same way, rewarding a library and board of legends, which makes the loyalty math coherent: a 5 base and a +2 that both defends and climbs steadily toward the payoff. The −11 breaks that internal logic on purpose. Where the plus and minus reward what you built, the ultimate steals what you did not: gain control of every nonland permanent, untap them, grant haste, and swing with an army assembled largely from your opponents' pieces for a single turn. It is a rare walker whose finish abandons its own value engine to raid everyone else's, and the climb to eleven is priced to make that raid feel earned.
