>>17493345I used MegaKhan, Dual Screens Klefki, Greninja and Specs Rotom-H (needed fire and electric).
Super easy.
If you memorize which sets each pokémon has, you'll do great, even the legendaries.
For instance, Tornadus spams Focus Blast, so Shadow Sneak with Greninja.
You'll get it eventually, don't give up!
