The Chameleon card becomes whatever you claim it is. It comes into play if someone calls “BULLCRAP!”.
For example: You play a Chameleon with a Jack of Spades, and your claim is “2 Jacks”. When someone calls “BULLCRAP”, the caller will lose because the Chameleon is played as a “Jack”.
However, if you play a Chameleon with a Jack of Spades, and your claim is “2 Kings”. A “BULLCRAP” call results in you losing. While the Chameleon is played as a “King”, you still have the “Jack” which makes your claim a lie.
