Mondrak, Glory Dominus

Doubling effects have always been priced with a discount, from Doubling Season on down: they do nothing on an empty board, so the cost of the multiplier gets subsidized by the payoff you have to assemble around it. This one breaks that convention by stapling the doubler to a 4/4 that pays for its own aggression, a body that attacks the turn after it lands rather than sitting inert while you build toward relevance. Doubling Season cared about tokens and counters both; Anointed Procession narrowed to tokens but is otherwise a mirror, an enchantment that does the same doubling on no body at all. What sets this card apart is not the scope of the multiplier but the chassis it rides on and the second ability, which is where the white in it becomes structural rather than decorative. Phyrexian mana on the activation lets a token deck fuel indestructibility off its own creatures, converting the fodder it generates into a counter that shrugs off wraths and burn. That is the real tension the card resolves: doublers are famously fragile, sitting targets that opponents kill before the engine turns on, so it hands you a repeatable way to make the engine survive board sweepers using exactly the resource it produces. The protection has a seam, though, and the seam is deliberate: indestructibility does nothing against sacrifice effects or exile, so an edict or a bounce spell still answers it while damage-based and destruction-based removal bounces off.
