Strategists: Nico Minoru, Doctor Voodoo, Dani Moonstar, Pixie, and Mysterio.

Vanguard: Ghost Rider, Blackheart, Man-Thing, The Hood, and Captain Marvel

Duelist: Taskmaster, Daimon Hellstrom, Satana Hellstrom, Kitty Pryde, and Ms Marvel (Could see Ms Marvel as Vanguard as well, but didn't want to double dip with Carol)

Plenty of others I would love, but limited myself to 5 for each role.
