God-Eternal Bontu

The whole God-Eternal cycle shares one load-bearing clause: on death or exile, each one may go back into its owner's library third from the top, not shuffled but tucked, so it can return on a known clock two turns later. The clause is optional, which matters more than it looks: you choose the reset when the recast is worth setting up, and you decline it when the library would be better left alone. Removal buys grace, not a clean answer. What sets the black one apart is the entry trigger, which converts permanents you no longer need into raw cards. It sacrifices any number of other permanents (never itself) and draws that many, so spent tokens, tapped-out mana rocks, and creatures already on their way out become fuel the instant it arrives. The friction is timing: the draw is welded to the enters-the-battlefield moment and cannot be banked for a fuller board later, so you cash in whatever you can spare right now. The entry payoff only refires when it actually re-enters the battlefield, so the draw rewards the recast, not the death. Exile reads like the intended out until you notice the same clause fires on exile too, closing that door when you want it closed; only effects that neither destroy nor exile, or that relocate it somewhere other than the library, genuinely remove it. It is attrition given a body: it eats the exhausted and refuses, on your terms, to stay gone.
