Replace Heatran with Groudon for better stats. Replace Giratina's thunder wave with toxic to cripple defensive Pokemon. Give Aegislash 252 HP/4 Atk/252 SpD sassy for a stronger gyro ball. Replace its swords dance and iron head with king's shield to lower opponents' physical attack and gyro ball for more power. Replace Kyogre's toxic and rest with ice beam to cover dragon and calm mind to raise special attack. Replace Xerneas's hidden power and toxic with thunder to cover Kyogre and Lugia and focus blast to cover steel. Replace Arceus's calm mind with defog to remove hazards.

That should be an answer! And thanks!

Answer 1

Replace Heatran with Groudon for better stats.

Gitatina: Replace thunder wave with toxic to cripple defensive Pokemon, like other Giratinas.

Aegislash: Give it 252 HP/4 Atk/252 SpD sassy for a stronger gyro ball. Replace swords dance and iron head with king's shield to lower opponents' physical attack and gyro ball for more power.

Kyogre: Replace toxic and rest with ice beam to cover dragon and calm mind to raise special attack.

Xerneas: Replace hidden power and toxic with thunder to cover Kyogre and Lugia and focus blast to cover steel.

Arceus: Replace calm mind with defog to remove hazards.
