Help me decide my 4th and 5th champion for necropolis (Red Goblin into Mantis paths)

I'm halfway done with necropolis and am starting the right side. I'm going to do the red goblin path into mantis mainly because I'm going to use beta ray bill for both nimrod and future ant man. I'm also for sure going to bring onslaught cause he takes so many fights and juggernaut for mantis, spiderman supreme, and grandmaster's reverse controls. Here's my current fight plan.

Onslaught 7* r4 - red goblin, kraven, squirrel girl, sunspot, kitty pryde
Juggernaut 7* r3 - mantis (or anyone but Juggs has a safer time intercepting), spiderman supreme
Beta ray bill 7* r2 - nimrod, future ant man

This leaves me with two team slots and in need of counters for silver centurion, spiderman 2099, sandman, knull, and shocker. Originally, I'd planned to bring kate bishop and chavez with this plan:
Kate bishop 6* r5a - sandman, shocker
America Chavez 7* r3 - knull (but she's mainly here for the kate synergy)

The problem is this leaves me without a silver centurion and spiderman 2099 counter, and I'm kinda nervous about taking knull with chavez. I guess beta ray bill could take silver centurion? and onslaught would be my main spidey 2099 champ? I'm not really sure who else I would take instead other than guillotine 2099 for silver centurion. My roster's below: are chavez and kate my best option or who would I take instead for silver centurion, spiderman 2099, sandman, knull, and shocker?

Does anyone who’s done the right side of necro have thoughts?

This was my last path which I did recently.

I used Sinister for most of the fights. He's reverse immune and also regens health easily, so even if he dies, you only need a level 1 revive to finish the fight and get back to 100%.
The rest of my team was FAM, Serpent, Apocalypse (just for HOA for Sinister), and either Photon or Kushala (depending on which path I was taking; I used this team for all 5 paths other than the Sentry challenge).

A few thoughts:
• I’d consider Vox over BRB. They take Shocker easily (not that Shocker really needs a direct answer tbf), can nuke through Spidey99 with degen, and will be much safer for Spidey Supreme than Juggs thanks to Vigilance. They don’t work as well against Nimrod because of the Debuff Immunity but I think he’s doable with Onslaught anyways if it comes down to it.
• Kate can handle SC if you’re particularly deft. The pseudo-taunt she has helps with baiting specials until SC exits Lock-on and as long as you maintain the Coldsnaps she’ll still be doing good damage that whole time. Certainly unideal over a harder counter with power control but she can do it. Definitely would do it better than BRB at least since SC goes Shock immune whenever he gains his Armor up Buff (you can temporarily disable it with Pulverize but it will always come back before you can start really stacking shocks).
• I’d definitely take Wiccan over Juggs. He does the same job of handling phase 4 GM with RC immunity, but also is a very good option for Knull. You don’t need Juggs’s extra stats for GM, and Mantis will be perfectly fine without his easy-bake intercepts.

All in all I’d personally consider going in with Onslaught, Vox, Kate, Chavez, Wiccan. A few of the fights are gonna sink a few revives but the right side of Necro tends to do that, there’s a few too many problem fights for you to get perfect counters for everything.

@Squidopus thanks for the thoughts. Will Vox work for future ant man? He’s who I’m most concerned about. Also, what’s the strategy for when using Wiccan for knull?

I didn’t use Vox in my run against Fantman, but they should handle him well as long as you manage the Nano-Armor ups. Vox’s ideal rotation involves alternating sp1 and sp2 anyways, so you just gotta stay on top of your intercepts. Keep in mind that the sp1 disabling isn’t technically a Special Lock so Vox isn’t immune.

There isn’t any particular strat with Wiccan against Knull, you mostly play him normally, just with the addition of avoiding blocking where possible because of the Necrotic boon. Build and pause your spells, stack Plasmas with sp2 whenever you can for damage, and use sp1s to regen off chip damage and extend your life a bit if you get low. It’s not super important, but it helps to push Knull to sp2 whenever you can because the 10 Armor Breaks become 10 Incinerates. You don’t have to worry about triggering Corruption if Knull does throw his sp1 since Wiccan is immune to RC and he prevents the Unstoppable + Unblockable Buffs with Neutralize, you just gotta remember that while it’s active you can’t trigger sp1 regen (it’ll just get replaced with Degen). You probably won’t get a solo, but you can do it in a few revives and relatively little stress since Wiccan takes care of a lot of the hard parts of the fight, and you can use Chavez as a backup option to help take Knull down.
