Comments

Replace Aerodactyl with Flygon for less weaknesses and u-turn. Give Kommo-O soundproof to nullify Swellows' boombursts and Kommo-O's clanging scales. Give Honchkrow a life orb for more power and 252 Atk/4 SpD/252 Spe adamant to raise special defense slightly. Replace dark pulse and flamethrower with sucker punch for more power and priority and pursuit to hit dark-weak opponents that try to switch. Give Porygon2 252 HP/4 Def/252 SpD calm to check special attackers like Salazzle and Swellow. Replace its charge beam, psychic, and thunder wave with ice beam to hit many common threats for super effectiveness, toxic to cripple defensive Pokemon, and foul play to hit physical attackers, especially ones using swords dance. Give Glalie 252 Atk/4 SpD/252 Spe jolly to raise special defense a bit. Replace its body slam and freeze-dry with spikes to hurt stuff when they switch and double-edge for more damage.

Give Flygon a choice scarf for more speed and 4 HP/252 Atk/252 Spe jolly to take advantage of its stronger physical attack. Replace its earth power and hidden power with earthquake and outrage for more damage. Give Honchkrow a life orb to power up its attacks. Replace Glalie's body slam with double-edge for more damage.
