Kossman,
I like that list you have there a lot! And it looks absolutely fun as hell to play with! I love how you abuse all of those cards in one deck...Vise, Crucible, Sphere effects, Null Rod, Magus, Welder, oh my! If this list has promise, I'd like to unofficially name it "19-Sphere". I know you only have the standard 9 sphere effects, but running 19 non-mana producing artifacts in a R/G deck deserves a sweet name!
Has Lumberjack worked out well for you recently? Or has he been a bit slow? His synergy with Root Maze does peek my interest. How's your match-up against brown decks? I ask because it seems that you're both trying to do the same thing, and I would put my money on a brown deck doing it bigger and faster. Another problem I see is that there's zero bounce/destruction. Which, I assume will be a problem once everyone and their mom goes back to Tinker->DS now that the Gushbond engine has been busted. Do you think there's room in the main by possibly cutting a Vise or something? Or are we straight 'balls to the wall' game one?
Also, would this list warrant mentioning on TMWA thread at

V/R,
Masta
