So, after getting through the region leaders tournaments with my In-game team, I've come across the World Leaders. I've been struggling at it, so I've decided to actually make a proper team for it. Anyway, here it is.

Forretress @ ???
252 HP, 152 Sp. Def, 104 Attack.
Impish Nature
- Spikes
- Toxic Spikes
- Stealth Rock
- Bug Bite
Will be the lead. Pretty much it will set up hazards, then Bug Bite until it faints.

Swampert @ ???
252 Attack, 200 Speed, 56 HP
Adamant Nature
- Earthquake
- Waterfall
- Brick Break
- Stone Edge
Kind of fast, bulky physical sweeper. The moves are just for coverage against as many types as possible.

Espeon @ ???
Magic Bounce
252 Sp. Attack, 252 Speed, 4 HP
Timid / Modest Nature
- Psychic
- Shadow Ball
- Signal Beam
- Morning Sun
First three moves for coverage, Morning Sun for recovery. Special Sweeper.

Please note that I am not particularly willing to go soft reset on legends to get right natures, or go find the DW ability on every Pokémon, so please do not suggest that. Looking for suggestions on all their items.
