When searching the deck for a card, because of a tutor effect, the interface is very unpractical to me, especially on mobile. I propose to have the ability to scroll a compact text list, like when you choose a name or a card type, which would show the card name and mana cost. I'll explain my issues.
Firstly, the browser shows ALL the cards in your deck, not just the proper ones. While I understand this makes the game more realistic and favors strategical planning, it results in an unproper behaviour of the slider. I often can't highlight the card I'm looking for, because the cards are too many and the slider isn't sensitive enough. For example, in the attached screenshot, I couldn't easily get to the Plains behind the Islands.
If I'm not tapping on the wrong card, I need so many attempts to get it right that I'm always running out of time!
Secondly, the "fan" opening of the cards makes impossible to properly look at their mana cost, which can be very relevant in the mid of a game.
A compact visual scroller (or the option to use it) would make the search smoother and improve the flow of the game.
