Deciding to spam revives to drain Kyurem of his PP, so that I could have my way with him to catch him, and finding out that "struggle" causes the user damage, and watching in horror as he kills himself. Not the best way to spend a half hour.
Having your Samurott get killed by Leavanny's critical hit in the battle subway, after your volcarona, which gets the first move in 99.9% of the time (with quick claw also) fails to down it, and then watching krokorok own the rest of my team with stone edge, hitting on three consecutive attempts, with a critical hit to the one remaining pokemon that's not susceptible to it. Pretty sure I've NEVER had that move hit three consecutive times.
Is it just me, or does every single pokemon in the subway have a powerful rock attack, and of course they never miss, unlike when you try to use them?
