There is not really anyway to practice as other champions you can duel have very different abilities.
Not really you chose to go unprepared Getting the evade charges is not hard if you know how to do the yo-yo trickYou also have the champs to do it even a rank 1 she hulk can do it Even now after the nerf she is still a viable counter Cap is another great counter
Save your units and wait until you have the right champs. Or your champs are upgraded. Hood, SyS R5 or CAIW R5. No point in rushing. That 3600 could of gone to Cavs to hopefully get the better champs. It’s not only skill, it’s bringing the right champs. On the paths where I could I brought R5 SyS And R5 CAIW no Units spent because I waited.
That's the main reason I love this boss, finally something in this game that depends on skill not RNG or money, and no matter how many units you pour in, unless you practice, youll never get better.
I personally have not beat him myself yet, the few times I did i refused to use any units and have only used items I have in the stash I can get him down to 10% no problem. I have the champs (Cap IW r4 5* and 6*, r5 Thing, 6* SS) for him but guess my skills are not good enough yet. The best I have been able to do is remove 3 of his indestructibles after 15 sp1s.
Kinda like the collector was when he was released.
