Oh Gunslinga, so we finally met and didn't even know it, this is Dontbiteitholmes from the Source and I played the mirror with you in top 4 and then split in the finals because I wanted the Recall.
He took the 2nd place prize of an Underground Sea, another Sea from my collection, and a Foil Batterskull I took the Ancestral and won the door prize earlier of a Mana Drain, because I'm pro like that (nah, just kidding, for real I just got lucky in the right spots and didn't play too sloppy, this was my first Vintage event)

On a related note I'm a big fan of Maze in this list.  Unfortunately I never got to draw it with a Trygon on the table but it did come in handy game 3 in the mirror.  When I looked at the lists from the GP I noticed most of the Tinker/Blightsteel lists didn't even run a Stripmine so their combo kill was completely dead to a Maze and it's pretty damn good against Predator.  I didn't like Cap at all and never brought it in, mostly because I never ever want to take out a Null Rod in any matchup where it's relevant.  The 4th Metamorph was killer all day, I don't think I'd run this list without it while BUG is still such a large part of the meta.  Glad I didn't run into Oath, so thanks for beating him.  The 3rd Null Rod over 4th Thorn is great.  Null Rod >>>>> Thorn so that was an easy cut IMO.  Wish I could post in the regular forums, I guess it's worth it to some people here to keep the noob count low, so maybe one day I'll jump through all those hoops.  The other deck in the top 4 was BUG with Gush/Blightsteel and he beat Salvagers to get into the finals.

I'd be interested in hearing what you like/dislike about the changes I made.  Like I said I don't play Vintage really, but I do play a lot of Legacy (a LOT) so this isn't my first time trying to metagame an Eternal SB.  So first off let me explain the SB

Jester's Cap was just a last second thought, and it would likely be the first card to go if I ran this list back.  It sucks with Null Rod out and I almost always want Null Rod out if my opponent is playing combo.

Tormod's Crypt/City in a Bottle was only for Bazaar decks, IE Dredge and Worldgorger.  I know Pithing Needle is "better" and Relic is "better" but I looked at the Dredge list that won GenCon and assumed people would pretty much bring the same 75.  So I noticed 8/10 SB cards that answer my artifact hate are CMC = 1.  So I like to have the option of Dropping a first turn Chalice @ 1 to protect my Tormod's or City.  If I play Relic and Needle I can't really drop Chalice @ 1 which means I have to hope they just don't have the hate card when I drop it, which seems bad.  As is with 2x City 1x Needle and 4x Crypt I can drop Chalice @ 1 and protect myself from Nature's Claim, Chain of Vapor, and Cabal Therapy and only have a 1 in 7 chance of drawing a dead hate card which seems better to me for some reason.  I need all the edge I can get vs. Dredge because the matchup is a nightmare.

Precursor/Revoker- I think 4 each between main and side seems right.

Pithing Needle- Revoker #5 and City in a Bottle #3.  Sometimes it is just better than any other answer and sometimes you just want that one more stifling effect.

Maze of Ith- Like I said, BUG lists usually seem to run 0x LD and Trygon Predator is a problem to which Maze is an uncounterable solution.  The fact this stops their wincon and is not terrible in the mirror (especially when you are my list and running zero of the huge+scary Hellkite/Trisk/Titan ect. MUD beaters) is just a bonus.

Open to criticism or suggestions on what to replace Cap with.  Like I said I can't post in the regular forums so anyone can feel free to help me out with this.
