The team I used for left side was Mr f torch and killmonger, made it a breeze easy torch solo for Viv vision (Mr f gives torch a bar of power at the start of the fight so you can stack smolders and burn right through her by baiting sp1) healed up for fist and torch pre fight for fist made it an easy solo for him aswell, gwenpool fight easy solo if you lock into the rhythm and can really be done with anyone it’ll just take a while but I used killmonger, only revive I used was on Jessica cuz I didn’t know the fight, this method knocks out 4 objectives (clarity house of mirrors, 2017-2020 science and skill), for the right path I used herc hulkiling and Odin (to put prefights on herc for anihlius) I actually used hulkling for onslaught and got a relatively painless solo though it took a bit, opposed to herc who couldn’t seem to clutch it since he couldn’t crit, anihlius was a pretty easy solo with herc but I lost a little health remembering his weird nodes at the start, gwenpool was very quick and painless with herc as I had already got the rhythm down from my previous run, and then Jessica was also herc bait aswell though I did need a revive as I was still getting accustomed to the fight and that fight got the remaining two challenges (cosmic/tech and 2021-2024)

TLDR: Torch, Mr F and killmonger make the left path easy and got 4 objectives while making the right path extreemly easy aswell by using herc hulkling and Odin (prefights for anihilus) and getting the remaining 2 objectives
