You have Hercules and CGR man! They can easily bypass the first 3 stage straight to the final one with their sp2! You should only take care to the Grandmaster fight
Spidey Supreme would definitely work imo, I see Wong but I have no idea how he fairs in that fight
I solo'd with both a r1 6* hood and Dr Doom, so Longshot should do fine, idk enough about wong and Spidey to comment.
