Sunspot, SL, DD, Jugg, Chavez you can replace but for consistency are important.
Good replacement are Green Goblin for Jugg and Gamora for Starlord probably it's better.
I did some changes from original deck during Destroyer meta (which is still active) to counter Prof X and lots of T5 things which are good counters to Wong. (That's why is DD so important you can plan defence or retreat).
When I am saying this is best Wong deck it is because other Wong decks are worse (in consistency) I didn't say they are useless but in current meta are weak.
Thanks to Black Panther and one of the worst new locations is this archetype harder to play than in early seassons. Cosmo Prof X Magneto Aero are extremely popular so good luck everyone. Nowdays are extremely bad times for Wong decks so it's probably better playing other decks. RIP Wonggers
