Comments

Replace Gengar's dazzling gleam with taunt to cripple status move users. Give Deoxys 4 Atk/252 SpA/252 Spe hasty to outspeed more stuff. Replace ice punch with ice beam for more power. Replace Groudon's stone edge with roar to prevent stuff from setting up on it. Replace Xerneas's thunderbolt with thunder to hit primal Kyogre harder. Replace Yveltal's shadow ball and roost with u-turn to reduce the need to predict switches and foul play to hit physical attackers, especially swords dance users. Give Genesect a choice scarf for more speed and 252 Atk/4 SpA/252 Spe hasty to take advantage of its larger physical movepool. Replace its extreme speed and techno blast with iron head for STAB and u-turn to reduce the need to predict switches.
