1. Visual bug and 2. Deck bug
After a recent update (not the small one from today, but a bigger one a few days back with i think at least >1.5 GB or so), some card sleeves and card styles have visual bugs. Also animations when i first saw it felt not as crisp as before.
Many times, when i try to play with friends, i can't choose historic decks that have certain alchemy cards in them. It would tell me, that the deck has non-format cards. when i toss out the alchemy cards, it works again. also when i set the deck to direct game it works too. this is pretty bothering, because i have set most of my decks to historic to play against randoms (it works with those) but when i play with friends it wont let me.
