Which route to go in getting to TB?

I recently acquired a 6* CGR (First God Tier Champ ever) but trying to decide which route to go with.
Should I rank up unduped 6* CGR to R2 or
Rank up unduped 5* GHulk to R3, Rank up unduped 5* Magik to R4, rank up duped 5* Iceman to R3. (I'm thinking these 3 champs what I going to need for Act 6 completion) I don't have a 5* Ghost, Quake, CG, and Medusa.
Trying to progress to TB.

I have BWCV, NF, CMM all 5* and fully duped and full sig.
5*AA, Apop, Domino fully ranked and duped
The rest of the 5* roster still at R1, which will take some time to get to R4

Currently at Act 6.2.4.
Any advice would be most appreciated!!

Only Magik for now, and try to awaken her. Rank up cgr if you want. Hold off on the rest

Cgr will end fights really fast

If you’ve learned how to play Cgr he’s awesome, but if you can’t figure him out then I’d hold off for now

Thanks every1 for the input. Gonna go ahead and rank up CGR and see if it will carry me through Act 6 to TB. Good luck to every1 this gifting event!!
