Oh Cradily, yet another victim of my crazy mastermind stalling Pokemon.
Ability: Storm Drain
EV's 252 Def 252 SDef 4 HP
Ingrain: First part of regaining health
Recover: Second part of regaining health
Giga Drain: Third part of regaining health
Confuse Ray: To confuse opponent making it harder for them to hit you.
I chose confuse ray over toxic because with this moveset, its better for you to give your opponent less of a chance to hit you rather than having them take even more damage. If your opponent hits themselves, then a combination of ingrain and leftovers, as well as either a recover or giga drain attack will heal a bunch of health, while confuse ray still will deal damage to the opponent if they hit themselves.
