This team looks pretty cool, but I do notice a few weaknesses. The most notable weakness is Sun teams. Venusaur alone can do incredible damage to your team, and it can setup on a lot of your Pokemon. Weavile also can't ohko it with Ice Shard (if you even run it), so that becomes a pretty lackluster check. To help with this I would recommend DD Dragonite > Haxorus
. I would normally advise against replacing your main sweeper, but since you have done it once already, might as well do it again to get a similar Pokemon but one that helps vs Sun teams. Dragonite is a fantastic Sun check, and is a very solid sweeper in general. I would use the set Remedy posted except use an EV spread of 252 Atk / 4 Def / 252 Spd.
This may seem like a very minor difference, but it gets Dragonite one more switch in to Stealth Rock. Some other minor moveset changes would be changing Red Card on Forretress to Leftovers
. While Red Card is nice, Leftovers gives a lot more overall utility and gives Forretress some form of recovery. Also while this is my personal preference, I would change Weavile's set to Ice Shard / Ice Punch / Brick Break / Night Slash
. Weavile is extraordinarily frail, making SD a really risky choice. It is often better to just go with more coverage + LO for power. Ok so Jellicent seems somewhat unnecessary on this team. Rotom-W and Gengar really do much of what Jellicent does, freeing the spot up for other checks. One note, if you do make this change I would make your Rotom-W Specially Defensive
Rotom-W @ Leftovers
EVs: 252 HP / 96 Def / 160 SDef
Calm Nature (+SDef, -Atk)
- Pain Split
- Hydro Pump
- Volt Switch
So at the moment you lack a reliable way to deal with Thundurus-T. In the rain it can spam Thunder's carefree and deal huge damage. I would recommend using Latias over Jellicent
. Latias is still a solid check to rain, and Keldeo, like Jellicent was, while checking Thundurus-T. Latias also check sun, giving you a secondary check. I would use a LO Pivot set on this team. Latias also maintains great offensive pressure, while acting as a great sponge, much like Jellicent.
