4. Scizor U-turn   I use the team like this: 1. Always use U-turn 2. Always notice the opponent emotion, use Main Attack on suitable time 3. Never let opponent success put stealth rock or boost up
When danger, for example someone dragon dance or else:
I don't know what to do...
It is bad
Can anyone help me out?
Long time no play PO.
After I make team, I only test it one time with pnve people.
Then I feel my team not as good as I think.
