Coulson only works against villains. So not him. Jean is a good lead, because is she gets one shot killed before she can cool down, she’ll redirect fully cooled and ready to go. Plus her debuff leadership is good. Then just go with great PvP chars. QS, Thanos 70 with Invincibility is good, Spidey T3, SW 70, Nova are all great. I hardly ever see support chars like Shuri, Coulson, Valk in TL. Only Wasp sometimes. But if you get past whoever else is on the team, Wasp is easy to 1 on 1.
