>>19960827A good strategy in pretty much any format outside of Triples is to have M-Kanga and support it. Here is the team I used:
Kangaskhan @ Kangaskhanite
Ability: Scrappy
EVs: 252 Atk / 252 Spe / 4 HP
Jolly Nature
- Return
- Power-Up Punch
- Crunch
- Earthquake
Milotic @ Leftovers
Ability: Marvel Scale
EVs: 252 Def / 252 HP / 4 SpA
Bold Nature
- Scald
- Dragon Pulse
- Rest
- Sleep Talk
Aromatisse @ Lum Berry
Ability: Aroma Veil
EVs: 252 HP / 128 Def / 128 SpD
Relaxed Nature
- Moonblast
- Trick Room
- Wish
- Protect
Crawdaunt @ Focus Sash
Ability: Adaptability
EVs: 252 HP / 252 Atk / 4 SpD
Brave Nature
- Waterfall
- Knock Off
- X-Scissor
- Swords Dance
Basic idea is just to sweep with M-Kanga. If it takes damage, Aromatisse's Wish heals it. However, my favorite strategy was to set up Trick Room when Kanga was paralyzed and continue sweeping by outspeeding pretty much everything. The AI never learns this strategy and continuously kept paralyzing Mega Mom, just to get swept. Under Trick Room, Crawdaunt also destroys everything. Milotic was there to stall because it works so well in Singles but I barely every used it. Just support your Kanga and you're good to go.
