I Have the Answer to Mega Malamar

I have the ability synchronize, so anything you give me I give to you!

Right after you succeed with that I decide not to follow the trend and use Confuse Ray

Then I Curse your entire State!

If you don't live in the U.S then your country!

I always win in the end!

I use skill swap on us quickly, so what you bounced at me is bounced back at you but your new ability is synchronized so you can't bounce it back and now you're cursed

i use Substitute.

It takes the split, meaning your move just fails and then I use skill swap with a Mudstale, getting Own Tempo and use Confuse Ray on you. Even though you have Synchronize I can't be confused, so your now confused and I'm fine.

Then I have my other Pokémon use status moves

I have my Gardevoir use Skill Swap with a Togekiss, giving it Serene Grace and then use a whole lot of Psybeams, almost guaranteed confusion for you now.

I use a Grimsnarl with Knock Off and then I continue Psybeams
