Depending on the situation, however, Sinister Serpent can be set to bait out your opponents cards like Thousand-Eyes Restrict, Blade Knight, Mystic Swordsman LV2, Mind Control, and so on
But even if you can only play this later in the game the Cabaretti seem to have enough going for them that this is always a welcome addition to the board
When dealing with a card type that can be commonly faked, its important to double check your source and make sure all the information lines up
