Rate my team please

Ok, for starters which tier are you using this in, originally i thought it was RU or UU until i saw the Ferrothorn. I mean using it in OU is fine if thats your style but i think there are a few team replacements you could make such as swapping Moltres for Zapdos or Nidoqueen for Nidoking but if you're doing it for your own style than i can relate.

Moltres is fine, it has good bulk with the HP investments so it can use Toxic effectively, it can heal itself and has dual STAB. My only concern is that if you are using this team in OU you would lose half of your health upon switching in if your opponent has Stealth Rocks up, which in OU is a popular thing. That's why i recommend using Zapdos instead, similar bulk, ThunderBolt and then Substitute while keeping Roost and Toxic.

Your Kabutops doesn't really need the Weak Armor/Focus Sash combo and would benefit more from Life Orb/Swift Swim due to his alright defence and the popularity of rain teams in OU at the moment which gives you further reasoning to switch Moltres with Zapdos. Otherwise he is perfectly fine

Sabeleye will probably want more of a Sp Def investment (so the 252 Sp Def, 4 Def) due to you having two physically bulky things already on your team so there doesn't seem much of a need to have a third while you can make him Specially bulky which in my opinion the current meta game is more focused on. I also suggest that you swap Confuse Ray out for a move that can deal damage so your not complete taunt bait from something like Tornadus. I personally recommend either Shadow Sneak or Sucker Punch so then you won't have to worry about its low speed stat as you will still have priority. As for nature i would say either Sassy or Careful due to them having a Sp Def boost while maintaing your attack stat.

Your Donphan is perfectly fine.

I don't really understand why you need Ferrothorn on this team, you already have a Physical wall and a Special wall (sort of). Sure he is immune to Toxic and has Leech Seed and his ability will wittle away at your opponents health but if you were to replace it you could play in lower tiers which could really benefit you. Some decent things you could use from UU include Rotom-H, Shaymin, Registeel, Mew, Empoleon, Deoxys-D the list is almost endless. But if you are going to keep Ferrothorn then i would have Spikes instead of two Stealth Rockers and Leftovers to keep your health up (most people fear the iron barbs and therefore go to special attacks instead so rocky helmet becomes useless).

Onto Nidoqueen then, it looks good but it doesn't really have the speed to need the extra investment so make it bulkier instead with more focus on the HP.

Overall a very solid team, well done.

-Since all of your pokes are UU or lower, I would take out Ferrothorn and replace it with evolite ferroseed and make this a UU team. Its tough to beat hyper offensive OU with this lineup.

-If you are playing OU, Rotom-w can hit this team really hard. You dont have anything to switch into it except ferrothorm however some Rotom do carry hp fire....

-Try putting a gastrodon in your team because A) the gastrodon/moltress defense cores. B) it is immune to water and can stop Rotom-W.

-If someone knows how to use Latios and Heatran combo correctly, Its a big threat to your team.

-Again consider replacing Ferrothorn and make this a UU team..

252hp/spD is best for sableye since willowisp stops physical hitters.

I used to use this set for sableye:

252hp/252SpD Calm Nature.
Moves : WilloW, Recover, Swagger, Foul play. Basically use swagger and hit them back hard with foul play. Works best on special sweepers. But I like your set better, its up to you what you want to use.

Sableye is such a broken poke, i hope it gets ban before Christmas.

Allen, Gastrodon is OU now so it can't be put into his team if he wants to bring it down a tier

Oh yea, thats right i forgot.. I knew gastrodon is gonna be a star one day when i first used it.
