When I use a mouse to click the edit button on a deck in the deck manager there is no filter button and therefore I cannot use filters. However when I used a controller to select a deck to edit the deck manager worked properly and the filter menu was where it should be.
Oh thats interesting, didnt even notice filter was gone, guess ive just tested the PvE matches. Can you test and see if you play SOLO PLAY - DAILY with the controler or if you get the same error "You cannot play that encounter"
