Oversized hand issue
If your hand gets too big, you basically lose the ability to accurately see anything in your hand, as there’s no scroll wheel search bar or anything, the cards just pile over each other (I don’t know about desktop, I’m referring to mobile). Someone just used peer into the abyss on me while I had about 190 cards in my deck, causing my hand size to go up to a touch under 100 cards. I was unable to put anything down because I couldn’t see anything in my hand. You should add an effect similar to the one used when one searches their deck for when the hand gets larger than a certain number (I’d recommend starting around 15 or so) to avoid making the game unplayable in such matches. It caused me to lose a match I’m 80% sure I could have won and I’m sure other people have had similar experiences themselves.
