You have Explosives to do that, plus maindeck furnaces to fizzle it's effect.. Plus you can just make inf mana, play all your creatures and cast Time Walk to kill on the extra turn with a hand full of countermagic...
Having said that, though, is it that hard to fit 1 Pyrite Spellbomb into the deck, to at least give you the option of the insta-kill? I'd also add 1 Lion's Eye Diamond to the deck, since it's just as good as Black Lotus when going infinite with Auriok Salvagers...
Isn't Time Walk an instant kill then? I mean, you grab 8 counters and your opponent never gets a turn again. I think Pyrite spellbomb would be a waste of space because it is simply not needed.
You don't need LeD because you have all those ways to grab the Loti..
I'm tempted to cut the 3 Aether Vials and add those two cards, and probably something like the 4th Brainstorm or 4th Meddling Mage. It just seems like this deck can't abuse Aether Vial as much as some other decks. Also, waiting 5 turns to be able to Vial an Auriok Salvagers into play is just bad...
Well, getting out Uncounterable Meddling Mage's and Trinket Mage's are quite powerfull.. But I agree, I think it's simply a poor choice because you have to wait a minumum of THREE turns before they actually do something.
