MANAPHY versus Primarina 7 star raid (2-Players strat) - Pokemon Scarlet & Violet - Primarene tera

Hi
i have tested some 2-players strats against Primarina seven star raid.
It´s just for fun, not the fastest strategy. But i would like to see my shiny Manaphy (from Pokemon Ranger) to fight against Primarina. ^^ Malamar for support is great because of his status attack Topsy-Turvy. This inverts the special attack stats of Manaphy before it heart swap it to Primarina. After this Primarina is on -6 special attack and make no more much damage, especially when we have light screen on our side :)
