Building a Jynx solo team

Sitting on 1.3 million dust, 274 RC, 19 FTMs and 9 CTMs. My main fire attacker is a 15/15/11 Entei with FS/OH, which was recently joined by a 14/13/15 Charizard with FS/BB.

The simulations suggest that I can only do FB/DK, using the above two, Arcanine with FF/FT, Gengar with Hex/ShB, Tyranitar with Bi/Cr and Scizor with FC/XS or Houndoom with Sn/FP. Against other sets, Gengar is too fragile and Arcanine is barely viable despite resisting Avalanche.

Candidates for powering up to replace the Arcanine (and eventually face the Regis):
A. 14/15/12 Moltres with FS/HW (needs 64 RC + CTMs)
B. 15/10/14 Moltres with FS/OH (needs 64 RC)
C. 14/14/10 Flareon with Emb/OH (needs FTM)
I am leaning towards the Flareon (which I used for prestiging back then) to save RC (far more precious than dust), but am concerned about its bulk despite resisting Avalanche.

In four weeks, I will no longer be limited to one Tyranitar, making Psyshock Jynx (probably) doable, if she is still a raid boss then. Is Crunch or SE better against Jynx (who is weak to both)? Of course, Crunch is necessary for Gengar and if I ever dare take on Alakazam.

This leaves Metagross with BP/FC as the final piece that would provide enough bulk, even for Avalanche. Been walking Beldum for over 400km and have around 180 candy, but yet to hatch a wonder (only caught attention).

(All team members are level 30 unless stated otherwise. IVs are listed as A/D/S. Simulations were Dodge Specials Pro with 25% accuracy.)
