It takes centuries to build the money , and right now I have 8 revives , 12 hyper potions , and a max potion . My game is saved right before facing Wallace and all my pokemon have full health. I can take your Wailord , but then crushed by his milotec . If faces his milotec my Wailord will switch out for Ludicolo , that takes forever to beat , and takes for my healing springs .
