Mystic/Cosmic Rank up

LONERANGER_141

So as the title says, I need suggestions choosing to upgrade 3 champs to r3. I have BWCV in mind (Hercules, juggernaut were suggested for the Grand master fight earlier, juggs for reverse countrol immunity). I am on Act 6.3.2 now and intend to be TB before July. Thank you
