Do you even know what Counter does >.>
Anyways, all sets are infinitely better with the use of Magic Guard. Synchronize is otherwise still better than Inner Focus (except for leads, but Fake Out usage has lessened by a lot).
All sets can use Magic Guard. Lead, Defensive, Choice AND Non-Choice Offensive.
Otherwise, Alakazam got no new SETS. Life Orb is much more viable, and it did get Psyshock. Future Sight is now more powerful than even Psychic, but has very, very limited applicability.
Inner Focus in helpful for Abra in LC to bypass the lots of Fake Outing there. I'm unsure if Abra can OHKO Meditite with Shadow Ball, however.
Otherwise, I do NOT recommend using Alakazam in Metronome.
