Heya, dropping in cause of me being a big-time competitor in MC, and although due to a loss am lol'd at, I'm willing to give a spiel about MC.
FIRST OFF, I've been compiling the main standards of the tier. Right now I have two set in stone and tested, if you guys care:
Golbat
Ability: Inner Focus
Item: Eviolite
Nature: Jolly
EVs: 248 HP, 12 Atk, 248 Spd
-Brave Bird
-Taunt
-Roost
-Toxic
Standard Lead Golbat. Golbat is boss with this set. Trust me on it; everyone back at Serebii runs this, and we lol at other leads.
Monferno
Ability: Blaze/Iron Fist
Item: Choice Scarf
Nature:Adamant
EVs: 12 HP,248 Atk, 248 Spd
-Flare Blitz/Fire Punch
-U-Turn
-Close Combat
-Thunderpunch, lol Iron Fist incompatible.
Doubt this set? Uturn on stuff like duosion, krokorok, even Kadabra. That typically OHKOs or gets close to. CC and FB are high-powered STABs for awesome, and Thunderpunch is mainly for hitting Wartortle. honestly, you just have to see it to believe it.
ALSO, EVs work like "4= one Stat IF first EV +1 Stat, then 8= one stat EV"
Ask me other stuff, I've got around 50 MC battles under my belt as of now.
