trade.
You have to trade it with someone for Kadabra to evolve, then you can trade back so you have Alakazam like in red/blue.
All you have to do is train it to a higher level and it will evolve on its own
Kadabra evolves into Alakazam when traded. (Abra evolves into Kadabra starting at level 16). Kadabra is #64 in the National Pokedex, and was introduced in the Generation I Pokemon titles (Red, Blue, and Yellow) where it could be found (Red and Blue Only) in Cerulean Cave, and (Yellow Only) on Route 8. In Generation VI (X and Y), Abra is obtainable on Route 5, but is a very rare encounter. ____ Kadabra does not evolve based on level; you need to trade it to someone else, then it will immediately evolve into Alakazam.
There is abra, kadabra and alazazam. Abra-kadabra=lvl 16 kadabra=alakazam=any level, trade pokemon, or on mystery dungeon, give luminous cave a link box.
