My Phoenix Regional winning team:
Francis the Garchomp (M) @ Lum Berry
Trait: Sand Veil
EVs: 6 HP / 252 Atk / 252 Spd
Adamant Nature (+Atk, -SAtk)
- Crunch
- Earthquake
- Protect
- Rock Slide
Francis, one half of my lead, works extremely well with his friend Louis, Earthquake hurts everything really hard (obviously except for Fliers/Levitators), Rock Slide is a great move that attacks both Pokemon and came in handy quite often during the tournament, and Crunch for any Dusknoirs or Bronzongs that I happen to come across.
Louis the Zapdos @ Chesto Berry
Trait: Pressure
EVs: 4 HP / 252 Spd / 252 SAtk
Modest Nature (+SAtk, -Atk)
- Detect
- Discharge
- Heat Wave
- Thunderbolt
Louis is the second half of my standard lead, Francis is immune to Discharge and it allows Louis to hit both opposing Pokemon and has a handy 30% Paralyze rate, Thunderbolt is there for just in case I don't want to attack my partner and don't want to mess with Heat Wave, which provides very good coverage for the team.
Bill the Metagross @ Occa Berry
Trait: Clear Body
EVs: 244 HP / 252 Atk / 4 Def / 4 Spd / 4 SDef
Adamant Nature (+Atk, -SAtk)
- Bullet Punch
- Earthquake
- Meteor Mash
- Protect
Bill could be called the MVP of the tournament for me, without him certain Pokemon would have caused quite a bit of damage to me, Bullet Punch, its resistance to Ice and Rock, were the main reasons Bill made it onto the team, and without that combination of things I may have been trounced from the tournament as early as round 2.
Zoey the Abomasnow (F) @ Choice Scarf
Trait: Snow Warning
EVs: 22 HP / 236 Spd / 252 SAtk
Timid Nature (+Spd, -Atk)
- Blizzard
- Energy Ball
- Hidden Power [Ground]
- Shadow Ball
Zoey keeps in the theme of attacking everything at once, but also serves several other purposes, it resists water, changes the weather, causes Focus Sash to be useless, and with the Scarf and EV spread shown, Zoey is able to outspeed Timid Max Speed Latios and below, some of which cause some major problems for Francis and Louis if they are outsped.
It's a very basic team that I created with a bit of inspiration from jeps, and not exactly original as the leads have been used in that form for quite some time, it wins with not only just straight up attacking, but attacking everything at once so as to not put all your eggs in one basket and targeting Protect users or a switch that resists an attack. Hits hard, fast, and gets the job done. Easy to use for beginners but still lethal enough to win against experienced players.
