Deck says invalid when I have all the cards to be able to build the deck. So basically while I was building some decks I found that even though I own the cards it gives me a "Invalid Deck" warning. "Teferi, Time Raveler" seems to be one such card that I cannot put into any deck I build regardless of the number of the card I put in my decks. So far I have seen 3 of these cards in total but I am sure there are more. Also for some reason i cannot add image files (png, jpg...) to this. But I have some screen shots and the deck lists if you want them.
I cannot build any deck at all, I have the cards for the decks, but every time it says "Wildcards needed to complete: x" - but I still have those cards and couldn't craft them with Wildcards if I wanted to, because I still own them.
So what's the point in playing, if you cannot build decks anymore? I don't get it, why I'm not allowed to do this anymore :-(
I'm getting the same thing. Here's my log.
