I noticed that it says "Electric E.E.L." in the top left corner. Is this a typo or a variant?

Well, it is a typo and I expected to see it become a variation because I figured it would get fixed. But even the second Coil Crusher card says the same thing. As far as I know, there isn't one without it, so I guess there is no variation. But I would keep an eye out just in case.

Well, the three-languages filecards from the Mexican cards all say Coil Crusher. Perhaps this is due to the fact that those filecards are a bit different to the regular U.S. filecards.
