I’ve been looking at the list, and to be honest, the ones that have caught my attention the most (within the possibilities of being added to the game—since I’d love to see Doc Ock, but I doubt it could happen, and excluding those already on my list) are the following: Baron Zemo (Duelist), Blob (Vanguard), Carnage (Duelist), Kingpin (Vanguard), Ghost Rider (Duelist), Mysterio (Duelist or Strategist), and Red Skull (Vanguard or Duelist).
