Depends on how many stones/$$$ you want to throw at the problem. XM team is ok for getting through and taking hits but given there's no native heart drop so you'll be starved for actives. Also Sherospada/Hysferzen could both use delays. The other floors aren't nearly as dangerous.
The reason Sephiroth is so good here is three fold: His leader skill is much easier to trigger with no worries of hearts getting in the way, his machine killer awakenings (pretty much 3x damage through the whole dungeon), and his active serves as a spike.
With XM even with haste, unless you're almost at system level efficiency you're going to run out of actives. You need to stall for inherited delays and have a Maeda Keiji available for the lockdown. Also even with XM's impressive damage you might still need an enhance to straight up kill MZeus.
If you have the cards running the Dacho carry isn't too bad. The trick is finding someone willing to carry you (a streamer does it for $5). You need A. Ra (or possibly June Ra) and 3 delays, a 3 turn, a 2 turn, and a 1 turn with all cards awoken (for skill boosts). The last slot is utility, I hear Tengu and LKali are good choices. Leveled is nice since it adds HP but isn't explicitly required if your carry is on point.
I soloed it for 10 stones with Rukia so it's doable if you want to throw money at the problem. I'll look for where I detailed the floors
seeing everyone working on that awesome farm team with Zeus dios makes me jelly. Feels like I'm getting left behind lol, probably won't even roll just to avoid getting my 5th sun quan.
