Check you Alakazam for the following things:
- Is it male?
- Did it have Recover the time you put it in the Day Care with the Sableye? Note that it should still have Recover, and that it shouldn't lose the move while breeding. To ensure it's passage, keep it as the top move on Alakazam
More than 90% of the time, one of these is the problem. If not, then you have glitched up the game somehow.
Hope I helped!
