2022-10-07 : Although Clandestine Chameleon has the abilities of ability stickers on other permanents you own and cards in your graveyard, it is not stickered unless there’s actually a sticker on it.

2022-10-07 : As ability stickers are added to other permanents you own or cards in your graveyard, Clandestine Chameleon will gain the corresponding abilities. Similarly, Clandestine Chameleon will lose abilities as those stickers are removed or those permanents and/or cards go to zones other than the battlefield or graveyard.

2022-10-07 : It doesn’t matter if the permanent or card with the ability sticker has lost the ability due to another effect. As long as it still has the sticker on it, Clandestine Chameleon will have the ability of that sticker anyway.
