You may have Chameleon enter as a copy of a creature you control, except his name is Chameleon, Master of Disguise.
Mayhem (You may cast this card from your graveyard for
if you discarded it this turn. Timing rules still apply.)
Chameleon is a mono-blue clone-on-a-stick: cast him as a copy of your best creature to double up on powerful ETBs, evasion, or stat lines. You build a board of value creatures, then leverage Chameleon (and other copy effects) to multiply the most impactful one, while Mayhem lets you rebuy him from the graveyard if he's discarded. The deck wins by snowballing card advantage and tempo until you out-resource the table.
Lean into copy density—add Sakashima of a Thousand Faces, Spark Double, Phantasmal Image, and Phyrexian Metamorph—plus a payoff creature worth copying like Consecrated Sphinx or Aetherflux-style engines. Tighten the mana with fast rocks (Sol Ring, Mana Crystals) and tutors (Mystical Tutor, Fabricate) to find Brudiclad for a fast token-copy kill. Finally, add interaction like Pact of Negation and Cyclonic Rift to protect the engine and ensure your doubled threats stick.
