Similarly, when Fairy Godmother Mystic Armorer from the Rise Of The Floodborn pack is in play, the strength of all your characters in play increases by three points, and if this card is banished, you get to return it to your hand, not the discard pile
These cards either need to be purchased directly from the shop or earned through events
If an opponent banishes a character you've brought to the palace, their character gets banished in turn
(4/29/2022) If no card is discarded, most likely because that player's hand is empty and an effect says they can't draw cards, the conniving creature does not receive a +1/+1 counter
Speaking of, I don't find its activated ability to be too great either
You can't hit man lands with it and most of the dorks you kill with it have either already got value from a come into play effect or cost less than the Decay making it not great as creature kill
