Alakazam does not get U-Turn. I was talking about partners which know U-Turn. Scouting, with U-Turn is a great way to give Alakazam a free switch in.
It is so frail, so even double switches are risky with it. U-Turn is a good way to get Alakazam in safe.
That moveset is also fine. Use Timid with 40HP/252SpA/216Spe, or maybe just straight up 252/252. Personal preference.
