After getting spirit of he badlands mirage and playing a monster it transforms into the mirage card remains in your hand as a purple copy that doesnt exist and also returns to your hand as a blue playable copy. The purple copy does not transform into a monster, is unplayable, and causes your hand to glitch because it technically shouldnt exist. This causes you to be unable to use cards in your hand as the game registers your hand as having one extra card. It also stays in the close up view of your hand even if you switch it to the left side view possibly blocking your heros health from view or blocking your hero power and not allowing you to use it.
