**Additional context**
@Hanmac, @tool4ever, @Agetian, @kevlahnota, I think this is my last big review of cards related bugs. I've tested a lot of decks in the Modern format. I realize that bugs will occur, many combos won't work with AI, and there will always be cards that are very difficult to code (like Prismatic Ending or Engineered Explosives). But I think I've covered the most basic things that can be fixed. Thank you for your work and for being so prompt in fixing bugs! I can still find something from time to time, but not on the same scale as in the last few weeks
