See attached screenshots. There are lots of problems making the game very difficult to play:

• All cards look white regardless of their color. This is especially problematic for lands in multicolor decks because it makes it difficult to see which color mana I have left.
• Some cards' names are invisible when they're in my hand. I have to read the rules text to figure out which card it is (since the art is also invisible), which takes more time.
• Some times when a triggered ability triggers, I can't see the ability.
• Other times when a triggered ability triggers, it says after it's finished making future abilities hard to read. This made me make a mistake, it asked me if I wanted to pay (1) but I couldn't read what it said, I assumed it was Go-Shintai of Ancient Wars asking if I wanted to deal damage to my opponent so I said yes, but it was Go-Shintai of Boundless Vigor asking if I wanted put a +1/+1 counter on target creature with shroud (which isn't possible because I can't target creatures with shroud), so I paid (1) for nothing.
• Some cards have their rules text invisible. In the screenshot it happened to the map token, but that also happens sometimes to my opponent's cards, making it difficult to respond to threats if I don't know what they do.
