If you're playing Serra Paragon or Outrageous Robbery, (or both at the same time) - cards that then offer a lot of options to play from the graveyard or exile, then the choice with a lot of cards in hand / graveyard / exile is seriously bad. Likewise when searching the entire library with some "tutor" spell. And I'm playing on a high resolution display on PC, I don't even want to see how it works in the mobile version. In this case, it would be much better to have the cards displayed as a simple line list (like in the old video game version from 1997) rather than a display simulating all the cards in your hand at once. The gray smoke effects (exile cards) don't exactly help clarity either. https://youtu.be/yZlC5ugr5eM?t=42
