Excuse me Obvious, but your chicken is adamant with only 4 speed EVs? Wow. I thought you were running Jolly max speed to hit 217 after a boost, but this is ... wow
That´s just 101 speed, 151 after a boost...only for reference, that´s slower than 164/780 Pokémon (21% of the Subway) and still slower than 15/780 Subway Pokémon after two boosts. How exactly do you handle an opening Aerodactyl Rock Slide flinch on wash machine?
Chicken is no Medicham whose LO HJK OHKOs even my max Atk/Spe Meta, there´s no way Chicken is OHKOing everything, I know it doesn´t (I´ve played thousands of battles with Hitmonlee´s 189 Close Combat, Chicken´s HJK is just 8% stronger)...
With max HP, Chicken is similar to Arcanine defensively (187-90-90 to 165-100-100) without taking the super helpful Intimidate into account. Yes Arcanine survives suprisingly lot, but not everything...then there´s CHs etc.
That team is really slow, 101-151-201 Chicken, 124 Rotom, 63 Scizor and 126 Hydra...
Good night. I know that it will be more difficult than usual to fall asleep tonight lol. I´m sorry, I just don´t get it.
