Camouflage Camouflage is a card that has pretty good flavor and tries to implement that into gameplay, but unfortunately it may just end up bending the basic fundamentals of the game a little bit too much for its own good
While, in specific contexts, they are the best cards the game has ever seen, our answer to this question actually lies outside of these cards
Today, most counterfeit cards are designed to pass various tests like the bend test and the light test, and some look almost exactly like the real thing, even upon close inspection (unless you're going really deep and using a jeweler's loupe, which is a good way to weed out fakes but too much work for the average player)
In Standard that's pretty great, you get three cards for the price of one
The ease with which you can enable this makes it one of, if not the best alternate win condition in Commander
Perfect for the aristocrats kill with Disciple of the Vault or turning all that colorless mana into an uber-Fireball
