Players interested in playing with AtoZ have a number of options open to them. They can of course pick and choose from AtoZ's and Decipher's cards freely to create their decks. They can also limit themselves to certain expansions. They can also get themselves a OFFICIAL ATOZ SEALED DECK. Here's how:
Start with the 20 Premium cards offered in Decipher's Official Tournament Sealed Deck. You may substitute up to 10 of these cards with any of Decipher's cards (but no more than 5 rares and no other premiums). This will allow you to get the personnel and ship base you want to go with your random cards. Then, write to me, Siskoid, and I will email you your AtoZ card list. You will receive 5 AtoZ booster packs plus one Enhanced AtoZ pack's fixed cards. Please specify from which expansion you want the boosters from (you may say 1 pack from A, 3 from C, 1 from F, for example.) and which Enhanced expansion you want your fixed cards from (you will receive one of the 4 packs at random). Each regular booster pack randomly assigns you 11 commons, 3 uncommons and 1 rare for expansions with more than 140 cards, 5/3/1 for smaller ones, plus a bonus card that may help you use one of the cards in the booster (it may come from ANY AtoZ expansion). NEW! Virtual packs available directly on the web for: A B (more will follow).
Sealed deck games may be registered here, and I will rank them here. Siskoid promises not to participate in registered Sealed Deck games. I'll rank regular games here as well. Games may be played online through a variety of chat mediums. Kedanya Station in particular offers some great playing areas. Have fun!
