Incubator Maker

Cards that incubate, producing Incubator tokens, which are artifact tokens with a set number of +1/+1 counters that can be flipped for two mana into 0/0 colorless Phyrexian artifact creatures with the same counters. Includes triggered creators like Converter Beast and Glissa, Herald of Predation, spell-driven sources like Chrome Host Seedshark and Sunfall, and saga-based mass incubation from Elesh Norn // The Argent Etchings. Distinct from tokens.creature_token_maker, which covers direct creature-token generation without the transforming-artifact intermediate step, and from tokens.clue_maker or tokens.treasure_maker, which produce different named artifact tokens with their own sacrifice abilities.
