Wave 1: Fine as is, but having Yellow Daredevil as the chase would've made more sense.
Wave 2: Switch Black Spider-Man with Peter Parker/Spider-Man.
Wave 3: Fine as is.
Wave 4: Dead Gwen Stacey , but seriously, Matt Murdock all the way.
Wave 5: Fine as is, but a Black and Gold Juggernaut would've been sweet.

Wave 8: Fine as is.
Wave 9: Fine as is.
Wave 10: Fine as is.

Wave 13: Make Kitty Pryde normal, and have the phasing one as a chase.
Wave 14: Skipped this wave, so it doesn't matter to me.

Wave 18: Probably gonna skip it.
Wave 19: Make Vision 1.0 solid, and have him phasing as the variant.
