Well, I was having fun with the game, until March 17th, when you decided to make almost every deck i have invalid for 1v1. Not only that, when I removed all the highlighted invalid cards, it still says its invalid and won't tell me which remaining cards are invalid so I can fix it. No cards are highlighted as invalid, yet it won't let me use the deck. Read on reddit that is a bug with the deck list, but is not fixable on mobile. So, maybe don't offer a mobile app that doesn't work. Imo
