Advice on Abyss roster...

So I am a cavalier player setting my sights on the Abyss as my next big piece of content to complete. This will take a while to save up revives, etc. but I also want to plan and take up the right champs. Obviously Aegon is a must to take in, but what other champs should I consider, and what are some problem fights that I need to find answers for?
Ps. Here are my 5* R4, 5* R5, and 6* R1 champs. Ive got plenty of rank up gems in the stash, and yes the Colossus is R5 but I'm waiting for the next level up event to get him that green star.

A good nullifier : Doom, symsupreme, claire
A good science killer : HT/void
She hulk can offset some of this but that still leaves some critical missing pieces for all easy lane fights.
I would suggest waiting to fill the holes and doing other content (variants)
All that before Abyss. Until then you will gather more champions to help you there
The way it was worded it was like you wanted to start next week or something 😂.
You could blitz trough labyrinth in the meantime though, I hear it’s incredibly easy with Aegon.
The OP still don't have the right champions for Abyss, so it's better to focus on those other areas
Besides, in terms of progression, Abyss should be the last thing to be done, unless you have the proper champions for it (which isn't the case here). I said it would cost much less than doing Abyss. You can even do some paths itemless with the right champions for it. I personally used items for sure, but no units for instances
Revives and potions are farmable, no need to buy them if you have a couple of them and are prepared to do 1 or 2 paths
