Crap, I don't know how to spell Equestria!
This is only in unglued because Wotc would NEVER, EVER, EVER make cards like these, no matter how balanced they are. I only know from the show the basics, so I may not have fit the card 100%, in which case I encourage all you who are more knowledgeable in the show to show me where I went wrong, I know some might think Twilight was not blue or black, but I deciphered that from how her magic powers were psychic and that once or twice her curiosity (blue) has cause evil (black) + blue black is the colors for psychic. And I made rainbow dash part blue because blue-red is the colors for things that are extraordinarily fast in flavor, like hypersonic dragon. Well, enjoy! (If I butchered the characters, forgive me, I only am trying because I felt inspired to do so.)
So, how did I do? (I will most likely make more for the whole set of main characters.)
Edit: Alright, attached the rest, don't think I forgot anyone!
