Online Version:
You buy the cards from a NPC Card Vendor. He sells Newbie Packs of 80 cards for 30 gralats or so and Supplement Packs of 8 cards for 5. Newbie Packs have a guaranteed mix of Magiks and common Creatures, Supplement packs are fully random but are your only way to get "rares". Once you purchase the Newbie Pack, you get a Deck NPCW which you can either fire anywhere for a Metris-style game or fire in The Card Arena for a Pokemon-Stadium-Style game, with your cards "coming to life" when cast. Advantage to this, it builds popularity for the cards and lets us work out the kinks-fatal combos, what should be rarer, what should be more common, what works, what doesn't. Also to keep people interested, maybe you can wager on your games? Each player puts the same amount of Gralats in, whoever wins gets to keep them all, log off and you lose half maybe? Or all? Hard to tell if it was malicious...
