New Redemption Grab Bag now includes an assortment of 500 cards from five (5) different expansion sets. Available at Cactus website.
I've considered hosting a tournament where everyone drafts/builds a T1 deck at the very beginning then we do T1 2P, T1 MP and TEAMS all with those decks. I take it you would be interested in attending such a tournament? We could even get a little tricky and allow people to adjust their decks in between events, but only with other cards they drafted (and for the TEAMS event, they could tweak their decks with cards their teammate drafted).
