I would recommend giving it as much rare candy as possible. Also, equip Zweilous with the lucky egg so that it could get extra experience points. Then find a good training place with high level trainers. The best wild pokemon to fight would be Audino, found pretty much anywhere that has grass (shaking grass), because they give out a ton of EXP.
Deino cannot evolve into hydreigon, they must first evolve into zweilous starting at level 50. After that zweilous can evolve into hydreigon starting at level 64.
