For PW teams, I believe that Dante is the best support, since it helps a lot after Maya Shield breaks and the Order In The Court DHC to Devil Trigger is pretty good. I don’t think Joe goes well with PW, but I think that you should use assists that could benefit both PW and Dante, when PW dies you can still fight back with Dante alongside other character. I would recommend Doom (Missiles), Iron Man (Repulsor) or Akuma (Tatsu). Other characters that might work imo would be Sentinel (Drones) or Magneto (Disruptor, for countercall assists).
I kinda liked the tech because of the reset with the Servbot super, but it wastes too much meter to get Frank at level 4 and you can’t get the crumple state from a throw with this team. Also, I don’t see Viper providing support after Frank gets leveled up besides an high/low unblockable with cr.M + Burning Kick assist, and if you try to save Frank she doesn’t have a safe DHC. While Viper is on point, Shopping Cart helps her a lot tho.
If you play Skrull/Frank, Skrull should be on point for an easy level up, but I don’t know how well Viper works at anchor position.
