So this team is meant to have Miraidon, Calyrex (Shadow Rider) and Flutter Mane to attack, while the other Pokémon support them. I ran Blissey since it has slightly better stats for HP and speed and frees up the item. Amoonguss since it gets Pollen Puff and Toxic. Indeedee pairs up with Calyrex. Pyschic surge and Expanding Force is really good with 120 Power. Then there is helping hand. With 120 BP and Helping Hand, it can KO both opponents even with neutral damage. I played two games with this team and won both.

Comments

I would put taunt on one of your attackers. If your supports get taunted, you'd be screwed.

One thing I'd quickly recommend is that Brute Bonnet is used over Amoonguss. It has better typing to deal with Calyrex-S and Lunala, which are common meta-relevant threats. Being able to resists both of their STABs and have Steel Tera to resist their Fairy coverage in Draining Kiss and Moonblast and hit back with Sucker Punch or Crunch isgreat. For the sake of Indeedee, use Crunch. I'll need more time to give a full answer though, which may not be as higher quality as others, since I mostly work around Trick Room in DUbers and not standard offensive teams like this, which is good don't get me wrong.

Miraidon does the same thing as you want while dealing more damage and getting Pokemon off the field immediately. Flutter Mane deals significantly more damage thanks to Choice Specs and can receive Speed Booster from Tornadus's Sunny Day, which can also weaken Kyogre and its nuke that is Water Spout and boosts Brute Bonnet's Attack, making it a huge threat. Life Orb Calyrex deals more damage off the bat and can survive for longer with Draining Kiss recovery, which is also effective coverage thanks to Tera Fairy. Your own Psychic Terrain can allow you to Spore with Brute Bonnet even if Miraidon is in play. Brute Bonnet is also just as bulky as Amoonguss and can better deal with Caly-S and Lunala, as mentioned in my comment. Indeedee was incapable of doing anything with Taunt so I changed its moveset to better support with redirection while being able to deal chip when Taunted. Calyrex would not gain much use from Weakness Policy due to its lacking Phys Def and the never-ending number of Incineroar as well as the lack of Fighting Types that are being used (in my own experience), so I settled with Life Orb for its wanted damage boost. Miraidon and Flutter Mane deal damage as you wanted and Calyrex with Tailwind can clean up before your food is finished warming up in the microwave.

Games are on my alt, which is low ladder, so the team is unable to be showcased against higher ladder. If you want me to grind on my alt for better games then I can do that within a few days of consistent gameplay.
