why dont you catch it yourself just get the membership card

i have two shiny darkrais, i will not trade them, but if you go onto http://serebii.net/ then go to wifi chat and talk to people through there and they might trade you there, but do not ask directly in the regular part or you will get kicked off, you click a name on the side and ten you talk to them there and ask if they have a darkrai, that is how i got mine the site is really fun and helpful

all right so here's the easy way to get darkrai.

1. make sure you have an action replay, and enable the walk through anything code

2. go to new moon island(or whatever it's called, the island where you go and see cressalia)

3. after you arive, go straight east, and after about 30 seconds of going, you'll arive on an island. enter the forest and there he is

4. just take the boat back the mainland
