Note: I was torn between putting this here or on the budget forum. It was built with 5-proxy in mind, but I wouldn't consider the 4 Shops qualifying for "budget." Also, in a fully-powered environment, I'm not sure how much blue power I'd actually run (so I'd probably only add the Pearl). With the exception of the Tinker targets, I'm striving for maximum consistancy, and the decklist is tight as it is. I can see removing 1-2 Chalice for blue power if it's necessary, but pulling Chalice is a metagame call as far as I'm concerned.
A few of the card choices:
Lightning Greaves - This was added while I was testing Metalworker, and are still there in anticipation of a random mirror-match to give me at least some edge game one. I'm probably cutting them for the second Mindslaver, but I wanted to present the list as I have it right now.
Pentavus - I love the synergy with Welder and the ability to chump block like a mofo.
Karn - He's an amazing clock and lets me go aggro, along with eating Moxen, but this deck seems to be in for the long haul, so Pentavus ended up getting the nod.
Platinum Angel - I was considering this, but I'm not expecting a lot of Dragon (plus the hate I already have in Chain, Stifle, and Crypt), and I seem to be able to handle the aggro matchup well enough, so this didn't make the cut.
Fire/Ice - The one qualm I have here is that it's the only spell in the deck at 2 mana (with the exception of the SB Pulse). With Chalice usually getting set at 2, it's often a dead card that can't even be pitched to FoW. If I leave the Chalice count at 4, I may consider trying to find a replacement. My options seem limited to the craptastic Arc Lightning or Lava Dart, though. I'd also like to fit the 4th of whatever I end up running in either the MD or SB some way or another.
