well... there is no such wonder mail but im sure there is one for action replay
i think you cant get that many....or you can just collect reviver seeds you can get reviver seeds at brine cave ...
you can only get max pure seeds with cheats.
my advice get lots of reviver seeds and teach ground moves to your starter Pokemon
There is not code. You have to get them in dungeons.
I would suggest lots of reviver seeds. Or level your Pokemon up a lot.
Use AR
no
I Have Just Defeated Dialga.. I Used...5 X-Eye Seeds And Sleep Seeds... That's It.....But it can help even more if you bring reviver seeds X-eye lasts about 4-5 turns
Use water types and have reviver seeds with you
you have lots of sleep seeds and lots of reviver seeds and you need to have a fighting and a water type starter
If you get Endeavor and a few Reviver Seeds, your set.
You should have some Reviver Seeds and some Status Seeds.
