Ok, so I just finished EVing a rotom for one of its specific forms.
Aaand then I realized that rotom forms can't be used on wifi for platinum. :<
They weren't programmed into D/P so it reverts back to regular rotom on platinums wifi. So I need someones help to see if rotom forms are aloud on HG/SS wifi via a trade. I googled it and stuff, but it looks like no ones tried rotom on HG/SS wifi.
The only other known way for rotom forms to go on wifi is through an action replay cheat, but that'll be my last ditch resort.
You can get the Rotom Forms in HG/SS in the Silph Co. Building, and i'm pretty sure you can use them on Wi-Fi, I'm not sure if it works like Giratina + Grisious Orb or not, I never use Rotom on Wi-Fi. =|
