Other legendary creatures you control have vigilance and ": Add one mana of any color."
At the beginning of your upkeep, reveal cards from the top of your library until you reveal a creature or planeswalker card. Put that card onto the battlefield and the rest on the bottom of your library in a random order.
Cast The Prismatic Bridge side and use its upkeep trigger to cheat huge creatures and planeswalkers onto the battlefield for free, snowballing into an overwhelming board. Alternatively, cast Esika to enable a five-color legendary tribal ramp deck that turns every legend into a mana dork. Either way you assemble a critical mass of powerful bodies faster than fair decks can keep up.
Add fast ramp (Sol Ring, Arcane Signet, mana dorks) and tutors (Demonic Tutor, Eladamri's Call) to deploy the Bridge on turn three or four. Optimize your nonland top-deck density so the Bridge never whiffs, leaning on a high count of impactful creatures and planeswalkers over situational spells. For a higher-power finish, include Tooth and Nail combo packages and protection like Heroic Intervention and counterspells to defend your engine.
