The game isn't available over here in Europe (it's not allowed for shops to sell the game, because of licenses), but my brother went to New York and bought the base game as well as expansion 2 for me. He also received 3 promo cards: Peter Parker, Deadpool and this one (Infinity Gauntlet) as well. So I think you should ask your FLGS. Good luck with your hunt!
I saw on Ebay that the Infinity Gauntlet is up for sale for about 20 and 38 dollars... That's insane!
Now you're talking about promo cards: is there a full list of Marvel Munchkin promo cards available anywhere?
I bought the game and both of its expansions. Is there any way to get the promo cards for a Spanish resident?
I'm little sad, now there are 5 promo cards that I can't obtain.
The last year, I bought the two promotional cards of Munchkin Adventure Time from boardgamegeek Store. Maybe I can buy the promos of Munchkin Marvel in the same way?
These will be retailer promotional cards primarily, or at conventions. Currently we just have a few advance cards, but you can contact USAopoly, or check with your local retailer about getting them. The X-Men and Howard The Duck promos should be coming soon.
