Let's not forget about the x2 Eggs Ex and x2 Butterfree Promo deck as well. Will heal 40 health with the Butterfree abilities, 50 health with Erika, and 20 health with Potion (40 health if used x2 same turn). That's 110-130 HP Regen. Combine that with one Energy to attack with Eggs.. Stack energy on both to swap them back and forth and passive heal 40 damage each turn.. If you get the right draw, it's literally game over before it starts. I'm 60+ wins with this deck against like, roughly 5 losses.
