The first thing that stuck out to me was blissey's defense investment. Honestly, I wouldn't invest any defense on blissey; its base defense is so bad that, even at full investment, blissey can still easily be OHKO'd by any physical sweeper worth it's salt. Put all that investment into sp.def and you can bring it out on any special sweeper and force a switch. Just make sure to switch when they bring in something to counter.
On that note, you really don't seem to have anything that can wall a physical attack very well. A mega-absol or mega-aerodactyl could singlehandedly tear apart most of your team, if not, all of it. Some good defensive options include:
a) Bulky sweeper Metagross with assault vest
Metagross @ Assault Vest
Ability: Clear Body
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Bullet Punch (Every metagross needs b-punch. that's just a fact of life)
- - - ??? (you decide)
b) poison heal gliscor
Gliscor @ Toxic Orb
Ability: Poison Heal
(get creative!)
c) shuckle. literally any shuckle set.
After that, I noticed that you also don't have a mega. While not required, I always like to have one on my team. I usually use a fast sweeper for my mega (Mega-Aerodactyl is a personal favorite of mine), but if you want to go for something a bit bulkier, mega-bastoise is your best option. I'll leave that decision to you.
Type-wise, your team is very well rounded. If anything, I would say maybe get something that is immune to or resists ground, but I wouldn't prioritize that as much as getting a defensive tank (or you could cover both with gliscor).
As for who to replace, I would suggest chandelure. Granted, I haven't used it very much, but in my experience, I've been disappointed with its speed and ability to take any more than a couple of hits (note: you might want to take this with a grain of salt, because I was quite a bit less experienced last time I used it).
Another option would be luxray. As much as I love its design, it suffers a similar problem as chandelure, and I've only really found success with it in the PU tier (I gave luxray more chances than chandelure because I couldn't get over how cool it was/is).
One final note: I would heavily recommend against having a full-female team. While attract is rare, and even rarer on male mons, it's always a good idea to try to balance out your team's genders so that nothing can shut down the whole team with attract.
Hope this helps!
