The deck is a four-color superfriends and creature-cheating shell. Jace, Multiverse Architect's −3, Identity Echo, Proteus Staff and mass "exile and reveal" effects turn cheap tokens or small bodies into the randomly revealed big creatures and planeswalkers that dominate the creature suite: eight-drop flyers, Agent of Treachery, Hullbreaker Horror, Ugin. Around that, it piles up planeswalkers and amplifies their loyalty with counter doubling, proliferate, flicker and double activations. Token-making sweepers and spells give it fodder to polymorph and a way to reset the board. How it wins: It cheats or casts huge evasive threats like Archfiend of Despair, Archon of Cruelty and Valgavoth to beat down, or it ultimates planeswalkers such as Nicol Bolas, Dragon-God's −8 or the extra turn from Ichormoon Gauntlet, while removal and sweepers keep opponents in check. Key roles: - Polymorph and reveal: Exile a token or minor creature (or a planeswalker with Jace, Multiverse Architect's −3) and flip the top of the library into a creature or planeswalker. This works best because the deck's creature count is concentrated in fatties and value walkers (Identity Echo, Mass Polymorph, Synthetic Destiny). - Token fodder and wipes: Token producers create cheap bodies to feed the polymorph effects. Several of them double as one-sided board wipes or indestructible protection for the remaining army (Martial Coup, White Sun's Twilight, Grand Crescendo). - Big payoff threats: Haymaker creatures that win the game or swing the board on entry when cheated in (Archon of Cruelty, Agent of Treachery, Hullbreaker Horror). - Loyalty amplification: Counter doubling, proliferate, extra counters per noncreature spell and twice-per-turn activations push planeswalkers to their ultimates fast. Nicol Bolas, Dragon-God copies every other walker's abilities, so the commander's card draw and polymorph get reused (Ichormoon Gauntlet, Oath of Teferi, Deepglow Skate). - Flicker and copy value: Blink and clone effects reset planeswalker loyalty, retrigger enter-the-battlefield creatures and duplicate the best threat. Displacer Kitten loops with the many noncreature spells (Displacer Kitten, Spark Double, Aminatou, the Fateshifter). - Library manipulation: Draw-and-put-back effects, starting with the commander's +1, filter hands and stack the top of the deck ahead of reveal effects. Shark Typhoon turns the noncreature spell volume into flyers (Brainstorm, Brainsurge, Shark Typhoon).
