Chameleon, Master of Disguise

📖 How to build Chameleon, Master of Disguise

Commander, Chameleon, Master of Disguise is a four-mana legendary blue Shapeshifter that can enter as a copy of a creature you control, though he keeps the name Chameleon, Master of Disguise. The game plan is to duplicate your strongest creature and double its impact on the board. His Mayhem ability also lets you cast him from your graveyard for {2}{U} if you discarded him this turn, so he can come back after a discard effect.

Build around creatures worth copying, since Chameleon's value depends on what you control. Blue interaction such as Counterspell, Negate, and Arcane Denial can protect your setup while you spend mana on him. Card selection like Brainstorm and Frantic Search can help you find creatures and discard fodder, and Rhystic Study can add card advantage to the plan. Mystic Remora, Propaganda, An Offer You Can't Refuse, Cyclonic Rift, Swan Song, and Fierce Guardianship all fit a controlling blue shell.

Watch for the fact that Chameleon does nothing useful without a creature on the battlefield to copy, so he is weak in a hand of only noncreature spells. Mayhem is narrow, because it only works on the turn you discard him, so you need to plan around that window. He also costs four mana and is legendary, so keep an eye on your board and your tempo.
