Well I think this deck is a master peice. I have not used it in a tournament yet but have play tested it vigouresly and it seems to always win. Although a Bargain Combo may be a little faster(I'm not sure). Still you should be able to get a turn two Sneak attack (montain swamp dark ritual). Then turn three put out some collosus or weatherseeds. If you used the collusus' then get a karmic guide out and put the collosus into play permanently. Or if you used the weatherseed'S then they come back to your hand so just reuse then at your leasur, even cast them on your opponents turn to chump block! But if the game gets drawn out use a rector to get out a bargain and get huge amounts of creatuures in hand and play then (even the dragoons to get more life and then more cards) to swarm your opponent. USe the Keys to reuse your collusus or the undertaker to get some creatures back form the dead.!!
The sideboard for this deck is so far non-existanr, please sen me some thoughts!
