First get a MOGI that is what I do and it works perfectly eathier TIGRE or MOGI then start raising one and get a jade stone then when it dies get another one give the heart to it it should be stronger then raise it health about 300 or 400 attack 600 or 500 or 700 then raise it's defense to about 300 or 400 then before you do all that stuff after it dies with the jade stone make it learn break spin in it's early stages then use break spin when you first start a battle then you'll be whipping butt!

Also you could use zans.
