Although there are 3 listed sources it is possible to acquire and use more than 3 at a time due to stock being refreshed and/or acquiring the card randomly as a reward. This should have been fixed in a patch but may still occur for some players.
In the final version of the third game, all copies of this card look identical. However, within the game's files there are fully complete textures for each unique copy of the card. It is unknown why these other textures were removed.
