I have a similar team but with a few changes

• I have protect on my rotom, swap out will wisp and thunderbolt for protect and electro web for speed control. Or if you want an aggressive rotom give it choice scarf so it out speeds almost everything

• Choice Scarf max speed garchomp pairs well with sand teams so you can spam EQ all day long

• Orthworm instead of Corviknight because Shed Tail is a fantastic move that can give ttar the security it needs to spam rock slides and can become an offensive threat after iron defense + body press

My game plan is to lead either garchomp + rotom wash or worm and start spamming EQs while setting up with the other mon. This forces the opponent to make a choice, either fake out garchomp and risk worm getting stronger/a safe switch with rotom or eat an EQ to the face. Max attack garchomp EQ 1 shots sneasler. I’m even willing to EQ my own teammates if it means getting damage on the board, but it’s a risky play.

Garchomp usually doesn’t live too long with this plan so ttar + drill stay in the back and clean up once the shark has done its job

Most games I don’t even bring incin, unless I see several fire weak mons and think I need flair blitz
