Hmm, I have a lot of bad luck in the Pokemon handheld games specifically, not the console ones. 90% of the time I get critical hits (I'm not over exaggerating), it's completely useless (When the opponent has red health and was going to faint anyways). When they get critical hits, it's the perfect time for them. An example is when a Pokemon is faster than me and will 3HKO me, I fully restore my health, they land the first hit, I can still survive two more hits. Then they decide to get a critical hit the second time they hit me, resulting in my Pokemon fainting. One funny thing that happened to my sister is that she had a Geodude, every time she used magnitude, it will be from 4-6, sometimes 8. When she fought other trainers whose Pokemon knew magnitude, they will always get magnitude 10.
