Charizard, if you are underground, stay there. If you are in the air because you used Fly, stay there unless it will not prevent from the winds and Blizzard. If you used two Protects or the being in the air will cause more damage to you then being underground, use Dig as Kangaskhan is Psyching Up to dodge from as many attacks as possible. However, if using Dig will not actually prevent you being hit by any attacks or the damage that will be prevented from Dig is less then the damage taken of the most powerful attack, use Protect instead on the attack that will do the most damage to you.
What I mean by this is, say the hole prevents me from getting hit by the Silver Wind and Hidden Power Rock, which is for all intensive purposes let's say it's 35 HP of damage and I'll get hit by all of the other attacks. But if the Blizzard does 40 damage, use Protect on the Blizzard instead of using Dig. That's just a for instance scenario so you understand what I mean.
But if you won't let me say that because it's not fair, use the Protect on the Blizzard since that will probably be the most powerful attack if Dig won't help you at all.
