My phone broke a month ago. I was two months into the game. Nothing transferred. So I dealt and started over. Trying for the whole month to get some of my decks back. Now I can't as most decks contained sphere kuriboh and shard oc greed. Why couldn't I finish going through my cycle and buy the 120 packs I had left. That would have been annoying, but acceptable. Now instead, I have no plans to ever play the game again until this is fixed. I didn't mind the grind to reobtain them, but with no hope of ever getting my decks back. I am done.
And my three other games all did. In the original game. No card was ever unobtainable. If the pack hadn't been out for years. I still had a way to get the cards. I love the game and would like to still play. Fix the transfer problem as I'm not the only one who had this problem, or let me trade cards before you get rid of some.
And cards are already rare enough when I have to go through six hours hundred packs to get three of an ultra rare. I don't think anyone would say that is easy.
