Hi drdev, this is about the card swiping, I have some recommendations...
In "full card mode", which I typically use, I think the space left/right to the cards is not necessary, you could really use the full screen width here. Also, things can look a bit confusing depending on what can be seen in the background. Maybe the background should be darkened even more. Or made (almost) white...
Look, I think this is visually confusing:

It's on a Sony Z1.
Also: If e.g. in booster pack mode, when I want to add a card via swipeup, it goes out of the full card view to ask if to pool/sidebar. I think it should stay in full card view and aks there. And then immediately change to next booster and stay in full card mode.
The question, if card should be added to sidebar or pool is maybe not necessary, you could either use swipeup on left and right side, or change the system by adding small buttons on top and/or bottom. Visually all has to be decent, to have all shining light on the cards

Buttons or similar I think are possible, because I think the devices aspect ratio is usually something at 16:9... and Magic card sizes are always the same. So you always have room on top or bottom.
Ah one more: I think a (subtile!) number indicator on how many cards can be swiped would be nice. Like "2/15"...
Thx

EDIT: Still one more idea: I think I already mentioned it, I think the deck editor could be prominently placed on main screen. It's currently so hidden. Very often I start Forge only in order to organize or review cards and decks...
