I don't know if you guys noticed, but in every new Rotom card's picture, there's a different rotom as well. Here's where they are:
Fan Rotom: Mow Rotom can be seen outside the window, the bottom right pane to be specific.
Frost Rotom: There's a Fan Rotom on the right side, partially concealed.
Heat Rotom: Frost Rotom can be clearly seen in the background.
Mow Rotom: You can see a shadow of Wash Rotom in the barn he's breaking out of.
Wash Rotom: Heat Rotom is sitting on the table in the background.
