Pokemon wih Air Slash can use Flyinium Z: Air Slash to become invincible for a turn, and water Pokemon like Swanna can use GX attacks multiple times thanks to Misty and Lorelei. You can do the rest in your head. And yes, while not completely invincible, I've done almost everything you can do. Axew is immune to Boss and Escape Rope, Scoop Up Net lets you put potential Boss targets into your hand, and Exeggcute lets you use your TAG TEAM trainers almost for free! Happy Trolling!
