Elspeth, Sun's Nemesis

The design conceit here is a planeswalker that never asks you to protect it, because it is built to die and come back. Escape rewrites the recursion math that usually pins down a four-mana walker: instead of drawing extra loyalty from a static or plus ability, this Elspeth arrives, spends its loyalty on a string of minus abilities, and then returns from the graveyard for a fixed escape cost paid partly in exiled cards. That inversion is the whole strategic axis. Traditional planeswalkers are a race against the opponent's board to keep them alive; this one wants to be attacked down, cash in its loyalty on tokens or a combat buff or a life buffer, and get recast. Note that every listed ability is a minus, so the loyalty is a spend-down clock by design: with no way to add loyalty, the card counts down toward the graveyard on its own, whether you drain it fast with a single big minus or grind it out with cheaper activations. The escape cost, four other cards exiled from your yard, ties the card's staying power to a grindy, resource-rich shell, which is precisely the kind of attrition mirror where a token-making, life-gaining, board-buffing engine earns its keep. It is a planeswalker reconceived as a repeatable spell, and the escape clause is doing the structural work that flashback does for sorceries: turning the graveyard into a second hand.
