In brightest day, in blackest night, No evil shall escape my sight. Let those who worship evil's might, beware my power, Green Lantern's light!!!
If you click on the game page and scroll down to the Statistics section, you'll see a Want Parts in Trade link. To get your request listed, type 'wizard miniature' in the Want Parts field in the User Information section. If you don't see that, you'll need to click Add a copy to your collection (it won't actually show up in the list of games you own unless you click the Owned box; you can just use it to show you want the piece).
Thanks, I'll do that. Never even thought of doing it, although thats probably because I've never had too, first time I've got a game thats out of print and missing pieces.
