Not sure what you mean by this question...
And have you been to the Deep Colosseum yet? You have to beat that 4 times, and then the 5th time around the final battle will contain the Shuckle. Despite it's lower level (45 compared to the early 70's of the rest of his squad), Shuckle has the highest Defence and Sp Defence of all Pokemon, and can just about survive a single Surf from Suicune (I did it by accident, but he just survived in the red, caught him the next round).
Be warned, the guy will use Earthquake which may wipe out Shuckle, and if you miss him you've gotta go through the Deep Colosseum another 5 times to get a chance at him.
