Auspicious Starrix

Mutate asked what happens when you stack creatures into one body, keeping a single set of stats and pooling their abilities. Most of the mechanic answered with a modest value trigger that fired each time you stacked. This design answered with the most explosive version of the idea, because its payoff scales with the pile itself. The mutate trigger counts how many times the creature has mutated and cheats that many permanent cards from your deck straight onto the battlefield: one the first time, two the next, more if the stack survives to be built upon. That escalation is the whole tension. Mutate shells usually want to spread mutations across several hosts to develop a wide board; this creature punishes that instinct, rewarding you for funneling every mutation onto one target so the counter climbs and the free permanents multiply. As an Elk Beast it is a legal mutate target on its own once it hits the battlefield, and the 6/6 body gives a growing stack a spine that survives combat while the engine spins. The trigger digs until it finds enough permanent cards, so lands, creatures, artifacts, and enchantments all count toward X and all arrive for free; only instants and sorceries get exiled and passed over. That quietly makes it a payoff for permanent-dense builds rather than a generic ramp piece. This is the mutate creature built to break open, not to grind.
