This particular section has recently caught my attention and I thought I would put forth my input. I understand that you are quite busy and I think the app is fantastic. One suggestion is that when in the deck building section is to not return to the deck after selecting a card from the search. I.E., I select {Fleecemane Lion} and it sends the selection back to my deck but I stay on the search page and can easily continue building.
Next version should have that.
Awesome! 👍
