In a fit of madness I pulled a couple more times right before and after the day changeover. Kind of glad I did...Rodin, Baldin, and Fenrir Viz.
Baldin makes my Minerva cheese team complete and capable of taking down every radar dragon in A3. Ilm would have also worked but Baldin is a useful enough inherit that my Saria's can make up for it if my partner has Red Guan Yu inherited on Minerva.
For those wondering the "optimal" Minerva Cheese team (all cards have 5 fire resist latents).

Revo Minerva (Awoken Sakuya)
El Dorado (Ilm)
El Dorado (Baldin)
Lifive (Awoken Hades or Hathor)
Charité (no inherit)
Revo Minerva (Red Guan Yu)
Ilm can be replaced by Saria but forces you to use Red Guan Yu for the burst, Red Guan Yu can be replaced by any three turn bind clear with Fire Dragon Swordsman being a really close replacement. Baldin can be subbed by Muse but Zeus Dragon is no longer a guaranteed kill. Lifive has a 25% gravity specifically due to the radar's damage absorbs. 30% is too much, and even 25% is too much until Sakuya is applied.
You need 5 turns of Bind Clear to survive Lifive's GTFO attack since awakenings don't apply to bound cards. Everything else is basically stall for Charite if necessary, then kill ideally with the boards given so you can save actives for dangerous floors. Floors 1, 2, and 3 are dangerous because bad spawns mean you can't stall up and tans will end you. Once the engine is up and running you should be fine. Use Guan Yu to clear poisons if it starts getting risky, but if there's hearts on the board it shouldn't matter if you match well. Oh and remember to clear jammers before Lakshmi, board change if you have to.
Radar Strats:
Heph: LOL
Hera: Charité then LOL
Noah: Charité, save bind clears for attacking turns then whittle to >30% then kill. DO NOT DROP HER UNDER 30%. Stalling works here too.
Gaia: Charité then whittle. Takes forever if she gets to keep delaying you but safe.
Zeus: Charite, then stall up everything, then Ilm (Or Saria/RGY), Baldin (or Muse), Awoken Sakuya, 25% gravity and smack him as hard as you can. Baldin's shield lets you survive the counter attack if he's in an unfavorable color. Then Charité. If you did it right he won't be changing colors anymore. stall and burst as needed.
I need more Minerva with RGY friends. BrianGriffin is the only one on my list.
EDIT: just took it for a spin in Ultimate Yamato Rush Mythical+ solo. Yep works like a charm. The gravities work to get around resolves, the shield is strong enough that even Tengu can't kill you once converted even if he binds 2/3's of the team. The biggest threat is Tengu or Diza flooding the board with poison. RGY or Saria clears that. I need more skill ups on the El Dorados. Lifive isn't as crucial though his double haste did keep me from dying on a flooded poison board. All in all a pretty relaxed experience for the one special dungeon that has given me the most trouble.
