.svg file download is taken down because there were several complaints that it wasn't working.
Anyway, here's the base for the popular MLP trading cards, so you can make a card of your OC, a background character, or whoever!
The font for the names, location, and occupation is called Celestia Medium Redux, and can be downloaded here: [link]
The font for the description is called Futura Medium Condensed.
Just Some Tips to make your card look as close to the original as possible:
The background is blurred a bit so the pony is the mane focus.
The background often has a grayish-blue gradient on the top.
The first letter of your description is larger, hot pink, and in CMR font.
To show the type of the pony, circle the symbol in white and make the word underneath (pegasus, unicorn, earth) white and bold (in the other formats I went ahead and did this for you). If it's an alicorn, highlight both pegasus and unicorn!
I left the symbol for the location blank, may add vectors for those at a later date, but in the meantime make sure you fill that circle in.
The pony on the front side has a small shadow underneath him/her.
If you would like a reference or example, here is the one I made: [link]
Feel free to use as much as you want, and be sure to ask if you have any questions
