That should work. Be careful stalling up Nene, there aren't a lot of safe places for more than a turn or so. Even still BHunters+1 should be enough on the final board if Raijin's available.
How are folks doing on the Cloud City challenge? I got through it yesterday. The 8th and 9th floor's were the worst for me. The final floor isn't as bad as it looks at first. Like the other challenges of this nature it felt more like a team building exercise than a skill check for the most part (though I'm sure skill opens up more teams, but I'm bad). Meri, Dmeta, and Pixel Seph were my MVP's for this set.
On the no leader skill dungeon I'd recommend just stacking prongs and killers and make sure you can heal if you need to stall skills up, a burst for the end makes it trivial if you can get one ready.
No awakenings was tough since you still needed a ton of damage so Dmeta did the trick, especially since you eat a preemptive right away. Also bring a true damage for floor 2 since you're not cracking 30 million def without a burst or awakenings. Leader bind immune badge means you can coast floor 3, or stall it out, both methods work. /you can stall out Minerva's combo shield too if you don't get screwed on hearts then smash her when it's gone. The last floor, a Haku-->Akechi-->Okuni bomb took care of Shedar.
