Populate

Cards with the Populate keyword, which makes a token that's a copy of a token you already control, letting you duplicate your best existing token rather than minting a new design. Trostani, Selesnya's Voice and Vitu-Ghazi Guildmage offer repeatable populate from activated abilities, Growing Ranks and Song of the Worldsoul populate on a recurring trigger, and Wake the Reflections is a one-mana spell that just populates. Many bundle populate onto another effect, like Sundering Growth destroying an artifact or enchantment first. Distinct from Token Doubler, a replacement effect that multiplies tokens as they are created; populate instead copies an existing token after the fact and only works when you already control one. Also distinct from Creature Token Maker, which prints fresh bodies independent of what you already have on board.
