Now that worlds are finally over, I can reveal the spreads I use on Lucario and Tyranitar at Nationals. I'd like to thanks Enosh and DeVon for helping me come out with these sets/spreads.
Amarok (Lucario)(M) @ Lum Berry
Ability: Inner Focus
EVs: 252 HP / 20 Atk / 100 Def / 4 SpD / 132 Spe
- Close Combat
- Bullet Punch
- Final Gambit
- Follow Me
Always survives Timid Scarf Salamence Fire Blast, Neutral Garchomp Earthquake and CB Talonflame Brave Bird. Speed hits a stat of 127 which outspeed Jolly Tyranitar and anything that tries to outspeed Tyranitar. Max HP allowed me to get the KO on anything with Base 70 HP or less with Final Gambit, specifically things like all Rotom-Formes and Mawile. Also puts Mega Venusaur in KO range for just about anything to KO it.
BugBear (Tyranitar)(M) @ Assault Vest
Ability: Sand Stream
EVs: 252 HP / 20 Def / 108 SpA / 4 SpD / 124 Spe
- Rock Slide
- Fire Blast
- Ice Beam
Surives 2 -1 Jolly Garchomp Earthquakes or 1 Critical Hit Earthquake. 252 HP 4 SDef lets it survive Timid Mega Lucario's Aura Sphere 15/16 times. 40 more Ev's were required to make this a 16/16 which is not worth it. 108 Sp Attack Quiet allows it to always KO 4 HP Garchomp with Ice Beam. 124 Speed was required to outspeed Garchomp and things that creep in that speed tier (Like Pyroar) after a Tailwind.
