I'm building this as a semi-casual deck for a weekly tournament. The tourney is mostly average to less than average players in the area. I'm not building it as a high caliber deck for power tournaments. The metagame is usually a few few fish decks, maybe a stax deck here and there, a gifts deck or two, and of all things, two-land belcher. It is also ten-proxy. The idea actually started after a conversation I had with one of the top vintage players in the area. We were debating which creature was the most powerful of all time. He claimed it was Goblin Welder, because it's so good in Vintage, while I argued for Dark Confidant, because it's good in every format. I started to think about how I could build a deck that utilized both. I've play tested a bit, but I probably won't have the chance to get too many games in before the next weekly tourney. Let me know if this deck has any potential. I also realize that the better deck would just be to go the full Control Slaver route, but I want something different. Perhaps there is something like this out there already, but I haven't followed Vintage closely so I've missed any deck that hasn't been one of the main threats in the format. I haven't really developed a sideboard yet, but it will for sure have several red blasts, Energy Flux, some creature kill in the form of Darkblast, Dark, or Fire/ice, as well as possibly Chalice (not in the main deck because I have so many 0 cost artis). Any sideboard suggestions would be nice. If its a hopeless deck just let me know, or if you see any changes that would work. Thanks for looking
