- fix for issue 348
- Fix a bug when going out of the deck editor then back to it again would show an incorrect color icon instead of nothing
- Fix a bug where the AI tries to play a spell with a target instead of just checking if it can play it. (visually, this showed as the AI tapping mana, then "freezing" for a few seconds with some cards grayed out on the battlefield)
