Nothing works as it should work, is WOTC using stupid Ai these days? Also the in-game bot you can use to test decks really needs an option to pick which deck the bot uses against you with the option of the bot using a deck the user has made even. The Japanese TCG Duel Masters that branched off of MTG in Japan, their digital format (A game called Duel Master's Plays) has a better deck testing bot than Arena does lmao.
