Help with synergy on sandstorm pokemon team?

Since you rate all my teams, I'll rate yours (I'd rate it anyways though...)

If you choose cradily/regirock, you already have 4 fighting weaknesses! Even without it, you have 3 weaknesses, and an easily pursuitable ghost (100/70 defenses). It could survive one pursuit but not another. And tyranitar can take a surf or two. Regirock would also add a 3rd water, ground and grass weakness.

You have excadrill (free set up?) and magneton to absorb electric types. and I can't think of an electric resist not weak to something 2 other pokemon are weak to. Except maybe lightningrod zapdos, but you'd need hiddenpower fire/ice because it doesn't learn any other good moves.

Another thing is you have three fire weaknesses, while one pokemon who resists fire is pursuitable, and the other hates being burned. You rely on jellicent a lot. I think you should have another fighting resist too. But I can't think of one not weak to one of the types that... yeah. Possibly zapdos can do this too. It doesnt share a weaknesse with a bunch of other pokemon, takes lecetric hits, takes fighting hits, and ground ones too. And 90/90/90 defenses aren't so bad with roost.

If you have problems with fire types, you could try heatran instead of magneton. You need skarmory because of conkeldurr and breloom. Heatran counters almost the same steel types as magneton (anything without earthquake), although it can't trap them. But it does stop ferrothorn, and possibly magneton. And actually does something to nonsteel types.

If skarmory is down, breloom and conkeldurr can beat this team easily. Breloom has bulletseed for jellicent, and if conkeldurr has guts, it also has a very strong payback and can heal with drain punch. Unless you get zapdos.

All that I can think of is zapdos... I don't think voltolos (that's it's japanese name) has enough defenses, and rotom-fan is just... Well you could just give rotom fan a balloon, and baton pass it a magnet rise. 4x ground immunity never hurts.

Edit: wow that was long and it only took me 10-12 minutes...

This is less about the moves on these pokemon and to see if the team works together well. I think it can but am not sure. Since this is a really wrong draft at this point any suggestions are welcome. Don't worry about moves here just the pokemon.

Tyranitar

Decent lead set up sandstorm...
