Musketeer Twisted Fate Multiple Cards [GAMEPLAY]

While playing against a Musketeer Twisted Fate I noticed that he always had 2 cards over his head. When he actually used his W it created another card behind the 3 that where already there in a way where we couldn't see what card it was. https://media.discordapp.net/attachments/378354080797425668/474860801640103936/unknown.png?width=1039&height=780 I had left the game and come back, but the rest of my team said they could also see it.
