Massive Rankup Help Needed

Gr8TonyStark

So I completed act 8 and thanks to banquet, I have 24 t6b and 25 t3a in overflow. I also have 2 6* 4->5 and 3 6* 3->4 gems.
Along with 3 7* 1->2 gems. I also have 5 6* ag.
I'm gonna begin with act 9 now.
Which 6 star champ shall I r5 and which ones to bring to r4.
Also which 7 stars to r2 and possibly r3 when I get the remaining t4a.










Thanks

I know that I shall focus on 7 stars but shall I also r5 fant, mags, doom, Kate, herc, cgr.
