Okay, I'll try to give some suggestions.
First off, if you'd like to build around Inteleon, you're going to need some sort of redirection because Inteleon is so frail that it'll need some help setting up focus energy. The three 'best' redirectors right now are Indeedee-Female, Amoonguss, and Clefairy, but in my opinion, amoonguss would not be the best here since grass types ignore Rage Powder, and Inteleon does not want to eat hits from the likes of Rillaboom and Kartana. There are two directions you can go from here, one with each type of redirector:
Clefairy is good at supporting fast, frailer sweepers because of friend guard. I'd probably replace Runerigus with Spectrier in this case. Spectrier is a great partner to Clefairy because it appreciates friend guard and follow me to keep it healthy, and can quickly snowball with helping hand and grim neigh boosts. Also, I'd 'merge' Toxtricity and Corviknight into Kantonian Zapdos. Zapdos is a popular partner to grimmsnarl because its good bulk gets even better with screens, plus Grimmsnarl's prankster fake tears can make it do tons of damage. Fake tears would also work well with both Inteleon and Spectrier too, so I'd swap it for fake out. Safety Goggles is on Zapdos because Spectrier already has the life orb, and Safety Goggles prevents venusaur from using sleep powder, helping our against sun teams.
Sample Team
Since Indeedee has the Psychic Surge ability, it works great with Hatterene (Instead of Spectrier) to set up trick room almost every time and prevents fake out to help Inteleon get set up better as well. Since you're setting trick room often, I'd swap Zapdos with a Trick Room sweeper- probably Glastrier. Glastrier is great on teams like this- it loves Dynamaxing in Trick Room, but you don't even need to set trick room- you can just set screens or use follow me to make it really bulky and potentially activate a weakness policy, or use a white herb to stop intimidate and follow me to protect it completely. You can choose which item you like best. Since there are less special attackers, you can give Grimmsnarl fake out, sucker punch, taunt, trick (and lagging tail as a held item) or whatever you like.
Sample Team
Also, I added Air Slash to Inteleon instead of Ice Beam, since it still hits grass types and gives you speed control. Dark coverage isn't that great right now either, so if yo want ice beam back, that's fine, or protect would be good to allow you to bring it in the back more often.
These are just suggestions, but I hope they help!
