Heaven forbid you post your roster when asking for us to suggest a team for you 🙃
Duped ghost can phase his specials. Make sure you bait heavies and wait to see if the parry sticks before attacking
Omega Red decreases tenacity chance by 10% per spore, so you won’t need to worry about him shrugging stuff off too much with him. Medusa and NF are great bursty champs that will put in work. Ghost is ghost, and Heimdall will give you a second chance. So OR Ghost NF Medusa Heimdall would be my team of choice, with NF being swappable with someone else you think would be good. Maybe Sunspot because of the nice BP?
Units. Lots and lots of units.
