Magic is a complicated game.
Implementing the game to Arena, the digital platform must be very difficult.
I totally understand that.
But, the amount of bugs and extremely frustrating user interface are not acceptable, especially on mobile.
When Scrying and Surveilling, the hand doesn't shrink and the most left card of the hand overlaps the library and graveyard.
Because of that, I can't check how many cards are in the graveyard.
When the stack is resolved, the card image is left on the stack location and never disappears sometimes.
During sideboarding, the app freezes occasionally.
During sideboarding, the black bar overlaps opponent library and graveyard and I can't check the cards in their graveyard.
During the game, the app freezes randomly, and starts to burn my rope.
During opponent infinite loop, my rope starts to burn because I have to resolve the stack and I lose the match, which is unacceptable.
Some of these issues have been around for YEARS!
WOTC, you need to bring more budget from Hasbro to build your team to address MTGA UI and bug fix.
MTG is a big business.
And big business should be done correctly.
Don't lose your business.
