I think you should start making anime cookies ... yeah.
Buet seriously, I think trading/gaming cards might go over fairly well. And it kinda fits in with the MTG theme you've got going over there. Keychains, small things. Unless you plan to advertise I'd try and stay away from more expensive things like graphic novels and the like.
You really do need to convince old whats-his-name to start advertising on the radio. All the magic nuts would come in droves. *sigh* So hard to find that stuff in the Rogue Valley.
Okay, I'm done now. c.c
