Sometimes, I go into the forums to enter a card I've made into a contest where I can send it in as a potential winner.
But you know what? I rarely find any contest to enter my new card in.
Pretty much, this contest solves that problem. Only 2 pieces of criteria:
1) Proper MTG language (I'm really picky about that one.)
2) They have to be good cards
Pretty much, all cards accepted.
