With that team, I think it’s doable! Your Loki is better than mine!

Getting Rick to Gold is a grind – 2 fights on 1.14 heroic and you get Pym badges guaranteed on regular 1.15 (or through Tony, Scott, and Hope through the Pym Lab building – you’ll need antfarms for that.)

Time might be more the enemy. Depends on when you started Falcon’s timer.

You do have to get Rick Jones to 3R to do the fight – he’d be your 1st cosmic tank.

Three of my team members are about level 43-44 – Thor is low at 36 off-setting Steve – so the event is doable at Academy Level 44. And 3 members are cosmic with 2 members that are science.
The thing is the rarity issue – so if you can field a team with gold rarity, you could do it.

My team after some adjustment is: Cap at lvl 49, 5R and skill upgrades; Teen Groot at lvl 43, 3R, and skill upgrades; Thor at level 36, 3R; Star-lord, level 44, 4R; and Spider-man at level 44, 4R.

I’ve used Rick Jones as well but he’s only level 30.

I’ve lost one fight so far and have 2-starred the map.

Good luck! I’ve been getting mostly 1 feather per fight, though I got one 3 feather fight. Apparently it’s possible to get no feathers. And each battle takes 7 energy things. So it’s really a grind.
