2 copy of Econ (even if I'm using 3 copies of them)
1 copy of Mirror Wall
1 copy of Sphere Kuriboh
1 copy of Champion Vigilence (the worst)
2 copies of Red Eyes Spirit.
Mirror wall and sphere kuriboh are annoying af, especially when you're getting screwed over by luck, you're about to make a comeback, and they reveal that card, and instead of red eyes spirit they should limit red eyes insight, and econ and srh are too good for a 4000lp 20card game. Should ban several toon cards too
Mirror wall is annoying but not overpowered. You can easily destroy the backrow.
Sphere Kuriboh is needed to prevent OTK combo decks. Phoenix would be out of control without Sphere Kuriboh.
