What you may be forgetting is that even if you don’t use Zemo for any fights, you get a 3% attack bonus for every villain on the team (so 15%) , and that is doubled when fighting heros to 30%. So, if you are really only thinking of using Juggs for one or two fights you have to ask yourself if he is going to make it so much easier for those fights it is worth losing the 15/30% bonus for every other fight.
I myself am running Serpent, Onslaught, Juggs, Void, and Zemo. I had originally planned to run D Thanos, but realized he only made maybe 2-3 fights easier than if I just used Serpent. So, a few extra revives on 2-3 fights was worth it to dump him and take Zemo instead, gaining the 15-30% boost.
Also, as someone reminded me above you can use the Thor relic on Serpent to gain an extra buff, which makes the fights where you need 3 buffs easier. So, struggle to think about why you would bring both of them vs. sub D Thanos for either Juggs or Zemo.
Thanos is better for the fights where you need a lot of buffs.
And the ones where you need a heavy after special. That's what I used him for. Otherwise same team as others have mentioned, Serp (R5), Ons, DThan, Nef and Zemo for the bonus. It wasn't bad at all.
Zemo can solo Abs Man fyi
I see a lot of people bringing Zeno. Can I ask what fights can he do or is good for?
I just brought him for the villain damage boost synergy. Mine is unranked.
