Replace Feraligatr, Arcanine, and Decidueye with Tentacruel for better speed and typing, Infernape for better speed and more moves, and Chandelure for better stats. Replace Pidgeot's quick attack with roost for healing and give it 4 HP/252 SpA/252 Spe timid to decrease its useless physical attack instead of its possibly useful physical defense. Replace Gliscor's protect with roost to heal faster. Give Magneton choice specs to power up its attacks, magnet pull to trap steel Pokemon, and 252 SpA/4 SpD/252 Spe timid to be able to one-shot stuff and avoid being hit. Replace thunder and signal beam with thunderbolt for more accuracy and fire hidden power to more reliably kill steel Pokemon.
