Wow. Two of the most useless pokes might actually be useful now! XD
Mega Beedrill Stats: 65/150/40/15/80/145
Moveset:
Beedrill @ Beedrilsite
EVs: 252 Attack, 252 Speed, 4 Sp. Def
Nature: Adamant
Ability: Swarm - Adaptability
Moves:
X-Scissor - with those maximized Attack EVs/IVs and, an Adamant nature, and Adaptability, this thing's gonna hit in UU like a mini - M-Lucario!
U-Turn - still hits hard, and makes sure that Beedrill gets a safe getaway at the same time of escaping fires.
Poison Jab - Poison might be a horrible offensive typing, but Adaptability, STAB, and a Massive 150 Attack stat mixed with maxed EVs Adamant might just fix it up!
Drill Run - Mainly just for Rock-types
Mega Pidegot Stats:83/80/80/135/80/121
Moveset:
Pidgeot @ Pidgeotite
EVs: 252 Sp. Attack, 252 Speed, 4 HP
Nature: Timid
Ability: Whatever - No Guard
Moves:
Uproar: Uproar makes all pokemon unable to sleep, which is really useful when Pidgeot's low on HP (Rest XD)
Heat Wave: Heat Wave. 100 Accuracy, 95 Sp. Attack values, and Fire, a hyper-offensive type. With no guard and Pidgeot's new high Sp. Attack, what could be better?
Hurricane: Hurricane used to be highly unreliable, but now, with No Guard and Pidgeot's offensive typing, Hurricane could cause serious damage to several UU pokemon at the same time hitting as hard as a Darkrai.
Rest: I'd prefer Roost, but Uproar fixed Rest's terrible side effect - Sleep. When fixing your HP when you have only 25% on your HP bar and Spamming Uproar, Pidgeot could actually be viable!
