In its own words

Incineroar is the only legal switch. It's forced.
Shortest explanation on record.
I'm faster than Gholdengo, and Earthquake is super effective, so it's the best attack. Gholdengo is at 72% and Mega Garchomp has 222 Atk with Sand Force inactive (no sand), so Earthquake probably does around 50-60%. It's unlikely to KO. Gholdengo would then hit me with a special move and knock me out, since I'm at 23 HP. Switching to my own Gholdengo is safer: it's immune to status moves and resists Shadow Ball poorly, but Make It Rain would be neutral. Dragapult (Ghost) takes super effective Shadow Ball from Gholdengo. My Gholdengo with Focus Sash gives a free hit, and Garchomp would be preserved at 12% HP, which is not much use. Still, Earthquake does real damage before I faint, which helps teammates. My Gholdengo switching in takes a hit, which may break its Sash. Dragapult is faster than Gholdengo and Draco Meteor would deal heavy damage, but it takes a Shadow Ball hit on the switch. Chip damage with Earthquake is better because Garchomp is nearly dead anyway.
Longest explanation on record.

Its own teams

Built by the model itself from the rules of each format. How teams are built.

draft 1 of 3six picked on attempt 1sets legal on attempt 1

"Kingambit with Swords Dance and Gholdengo with Nasty Plot are the late-game finishers. Incineroar (Fake Out, Intimidate, Parting Shot) and Corviknight (Roost, Defog, U-turn) give pivoting and bulk. Mega Garchomp and the Focus Sash Dragapult supply fast offense."

draft 2 of 3six picked on attempt 1sets legal on attempt 2

"Only Incineroar's illegal Knock Off needed fixing, and I replaced it with Darkest Lariat, which it can learn and which ignores the target's defensive boosts. The rest of the plan is unchanged: Kingambit and Garchomp set up and sweep, Gholdengo and Dragapult add special offense and speed, and Incineroar and Corviknight pivot and provide bulk. All items are different and all Stat Points are within limits."

Attempt 1

  • Incineroar can't learn Knock Off.
draft 3 of 3six picked on attempt 1sets legal on attempt 2

"Incineroar leads with Intimidate, Fake Out and Parting Shot to pivot, while Kingambit and Mega Garchomp provide the main physical pressure. Gholdengo (Scarf) and Dragapult add special coverage and speed against Fairy, Steel, Dragon and Ghost types. Corviknight is the defensive Flying/Steel pivot, with Roost and Bulk Up to wall physical attackers and Body Press to hit back. I removed Knock Off and checked that every move and item is legal and used only once."
