Thank you for your help. And how do I put them in spoilers to lessen the space?
Here are each of my 50+ win teams. I actually did not have all the right nature on my Pokemon either due to lack of access. or just being plain lazy in breeding, so I am listing the optimal nature and the one I actually used due to laziness. As you will notice, one of my Battle Tree philosophies is that none of my guys will share a weakness, since the AI will try its best to exploit if there is one.
Team Mega Mom (Super Singles)
Kangahskhan @ Kanghaskhanite
Ability: Scrappy --> Parental Bond
EVs: 4 HP / 252 Atk / 252 Spe
Brave Nature (Adamant Nature)
- Return
- Fake Out
- Sucker Punch
- Brick Break
Garchomp @ Life Orb
Ability: Sand Veil (Rough Skin)
EVs: 252 Atk / 4 SpD / 252 Spe
Naughty Nature (Jolly Nature)
- Earthquake
- Crunch
- Dragon Claw
- Poison Jab
Tapu Lele @ Choice Scarf
Ability: Psychic Surge
EVs: 4 Def / 252 SpA / 252/ Spe
Hardy Nature (Modest Nature)
- Psychic
- Moonblast
- Energy Ball
- Thunderbolt
Usually Mega Mom and Garchomp can just mop through everything. Tapu Lele is there as an insurance finisher. Lead with Mega Mom, Fake Out then Return usually knocks out someone. She can usually knock out someone else before going down thanks to her single weakness that the AI has a hard time exploit. Garchomp and Tapu Lele are basically "coverage for whatever you have left."
Team Mega Medicham (Super Singles)
Medicham @ Medichamite
Ability: Pure Power
EVs: 4 HP / 252 ATK / 252 Spe
Jolly Nature
- Drain Punch
- Bullet Punch
- Zen Headbutt
- Fake Out
Xurkitree @ Choice Scarf
Ability: Beast Boost
EVs: 4 HP / 252 SpA / 252 Spe
Naive Nature (Timid Nature)
- Thunderbolt
- Energy Ball
- Dazzling Gleam
- Signal Beam
Suicune @ Leftover
Ability: Pressure
EVs: 252 Hp / 156 Def / 152 SpD
Quirky Nature (Bold Nature)
- Scald
- Calm Mind
- Rest
- Sleep Talk
I found that Suicune is VERY VERY good in the Battle Tree. With only 2 weaknesses, it is very difficult for the AI to exploit. I finally lost when it went down to Scope Lens Musharna that hit it critical hit Energy Ball every single time. The team leads with Mega Medicham, who can usually sweep by himself. I went with Drain Punch over High Jump Kick because consistency is the name of the game in the tree. Anything Mega Medicham couldn't sweep means Suicune can stall out. Suicune would use Scald against physical attackers to try to burn, or just spam Calm Mind against special attackers. Xurkitree is there to act as a finisher by going all out on coverage moves.
Team Mega U-Turn (Super Singles)
Beedrill @ Beedrillite
Ability: Swarm --> Adaptibility
EVs: 4 Hp / 252 Atk / 252 Spe
Jolly Nature (Adamant Nature)
- Poison Jab
- U-turn
- X-Scissor
- Brick Break
Landorus-Therian @ Assault Vest
Ability: Intimidate
EVs: 252 Atk / 4 Def / 252 Spe
Lonely Nature (Jolly Nature)
- Earthquake
- Stone Edge
- U-turn
- Fly
Suicune @ Leftover
Ability: Pressure
EVs: 252 Hp / 156 Def / 152 SpD
Quirky Nature (Bold Nature)
- Scald
- Calm Mind
- Rest
- Sleep Talk
This is a modified version of the last team. Beedrill's job is to either OHKO, and if it can't do that, then U-Turn (usually into Suicune). Landorus job is to Intimidate, then U-Turn (into Suicune). I realize by now that Suicune is completely cheese in the tree, that is why Landorus replaced Xurkitree to further support it. Against anything that doesn't immediately threatens Suicune, it just means Calm Mind 6 times, rest up, sweep. And almost any Pokemon that naturally threatens Suicune are ones that naturally get OHKOed by Mega Bee or Landorus. Suicune can really carry lots of teams into 50 wins just by itself, so I might bench it from now on to give other guys a chance.
Team Megazard Why (Super Doubles)
Charizard @ Charizardite-Y
Ability: Blaze --> Drought
EVs: 4 Def/ 252 SpA / 252 Spe
Timid Nature
- Heat Wave
- Air Slash
- Solar Beam
- Protect
Garchomp @ Life Orb
Ability: Sand Veil (Rough Skin)
EVs: 252 Atk / 4 SpD / 252 Spe
Naughty Nature (Jolly Nature)
- Earthquake
- Crunch
- Dragon Claw
- Protect
Xurkitree @ Choice Scarf
Ability: Beast Boost
EVs: 4 HP / 252 SpA / 252 Spe
Naive Nature (Timid Nature)
- Thunderbolt
- Energy Ball
- Dazzling Gleam
- Signal Beam
Kartana @ Focus Sash
Ability: Beast Boost
EVs: 4 HP / 252/ Atk / 252 Spe
Naughty Nature (Adamant Nature)
- Smart Strike
- Leaf Blade
- Sacred Sword
- X-Scissor
75% of battles were just Heat Wave + Earthquake, repeat. Otherwise, Protect until the other guy can finish the job. Grass attacks on 3 of my guys because Megazard Y just really really hates Rock. This team is just all out aggression, it's probably the team I have that can get to 50 wins in the shortest amount of time.
Team Sand Explosion (Super Doubles)
Garchomp @ Garchompite
Ability: Sand Veil --> Sand Force
EVs: 252 Atk / 4 SpD / 252 Spe
Naughty Nature (Jolly Nature)
- Earthquake
- Crunch
- Dragon Claw
- Protect
Gigalith @ Life Orb
Ability: Sand Stream
EVs: 252 HP / 252 Atk / 4 SpD
Careful Nature (Adamant Nature)
- Stone Edge
- Earthquake
- Explosion
- Protect
Azelf @ Psychium Z
Ability: Levitate
EVs: 4 Atk / 252 SpA / 252 Spe
Docile Nature
- Psychic
- Thunderbolt
- Explosion
- Protect
Celesteela @ Assault Vest
Ability: Beast Boost
EVs: 252 Hp / 252 SpA / 4 Spe
Docile Nature (Modest Nature)
- Flash Cannon
- Fire Blast
- Giga Drain
- Air Slash
The Garchomp was a straight import from the other teams. Depending on situation, first turn is usually Gigalith Protect/Garchomp Earthquake or Garchomp Protect/Gigalith Explosion, but the team plays very flexibly depends on the match-up. Both Azelf and Celesteela can switch in while a guy is using Earthquake. 3 of the guys are tanks, so the team won many battles based on attrition alone. This is my favorite team because everything just kind of works together seamlessly.
