Just be warned that the prebuilt decks are mega powerful. Spriggan used one against me, it wasn't right pretty. Otherwise, it was good. The bugs me and SE encountered didn't show. It is pretty good fun.
Idea!
We could do a online tournament with this. I know you Utah people don't need an online tourney, but i like planning this sort of thing out. Anyway, up to 8 people meet and use Netdraft to get their cards, between 3 and 6 packs worth. That's done in a interface where a list of cards appear and people choose them, and only when each person chooses one do you move onto the next card. Then a game is played, after the decks are made and assembled, and it's done with winners then playing each other and losers playing each other. Since its online and the decks are saved, we use the security codes to make sure people don't change the deck between games and can simply arrange times for the next round of games on the forum.
It would be easy to plan, more difficult to get the times sorted. But pretty fun. And it costs nothing for the cards.
