I feel like Groudon would be better focusing on one of its attacking stats rather than both, a SpD lowering nature is never good unless you really want to die, like a Focus Sash, Endeavour Whimsicott. I mostly agree with Thundet, but some of the sets are weird. The Groudon definitely needs protect and I would consider Fire Punch over Heat Crash, just because its more consistent. Stone Edge is also far too unreliable with that accuracy. Tho idk what to switch Eruption to and you really need Tailwind on Whimsicott to allow your Groudon to sweep with Eruption if you keep it (and maybe make it a a special attacker???).
For Whimsicott, you really need Tailwind. Thats basically Whimsicott's reason for most teams. And your team really needs the speed control. I think Covert Cloak is a better item for it, and Sash on Smeargle instead. For moves, I don't know how or why, but yours has Follow me which it should not be able to learn. A better moveset would probably be Moonblast, Taunt, Encore and Tailwind. It does depend on what you want it to do, I've run the Sash Endeavour set before, as well as the above set. For EVs, it wants speed if you're using it against an opposing Whimsicott/Tornadus, and it also wants bulk if you're not running the Endeavour set. Also, if Tailwind setter is its role, you should also consider Tornadus.
Now, for Xearneas, Power Herb Geomancy D-Gleam/Moonblast. Max speed and special attack. Timid Nature. I don't understand why you wouldn't.
Kangaskhan is ok, but it definitely needs protect. Replace Earthquake, it has a lot less use on your team because you only have 1 ground immunity to spam it next to. And if it can, run Power-Up Punch instead of Drain Punch, I don't know what your format is so I dont know if its legal. So it should be Fake Out, Drain Punch/Power-Up Punch, Return and Protect.
Smeargle should be max speed Jolly Nature with Focus Sash, Follow Me, Spiky Shield, Fake Out and Spore/Dark Void (if legal, again, I dont know your format). Moody is good for it so don't change that.
I actually have used Corviknight before in a gc but as a TR attacker so I'm not sure that'll help but still cool to see someone else use it. Though, I'm not sure what its role is on this team. You have Light Screen for Special Bulk, but you also have max defence without Body Press. And Red Card?????? If you want an anti-Xearneas tool, Bronzong works (see WolfeyVGC's video on how he won the 2016 World Championships), and also Crobat (again, see WolfeyVGC's video for best poison types). Otherwise, it can set up Tailwind and also spam Iron Defence + Body Press. For item, maybe Safety Goggles, Rocky Helmet or Sitrus Berry if its support? And if you have a reason for Red Card, could you reply to say it because I dont see much of a use. Also if it is Anti-Xearneas, it should be max Special Defence, not physical because its a bit slow and Xearneas might be able to kill it before it can set up Light Screen.
