Ok, a few things concerning your team, I think you should actually replace Meowstic with Cresselia, as it bulks up your team and can also run Skill Swap, which is very useful if you have a P-Don on your team. I also think just stowing Trick Room and going for tailwind with a 252 speed groudon may be an idea, which allows you to fire off eruptions (preferably at full health) which leads me into....

Eruption/Overheat > Fire punch
Although you are running off Groudon's immense attack, these two just have so much more power and Groudon just has a large SpAtk anyway that it doesn't matter. Eruption under tailwind is great as well

no thaks.i want stay in trick room,i have alredy a team based on tailwind,without any primal or rayquaza,for fun.cresselia is more bulky yes,but not have prankster,and not know if can have the same moveset,maybe i can use whimsicott like meowstick and use cresselia for trick room,skill swap,ice beam, and another move.
