Combo Engine!

Hey there Vintage folks. So it's been a long while since I've posted a new decklist on these forums, but I'm looking for a way to answer the current Vintage format that doesn't suck. This search has led me to a card that I think deserves breaking and it is called:

Wurmcoil Engine

Artifact Creature - Wurm

Deathtouch, lifelink
When Wurmcoil Engine is put into a graveyard from the battlefield, put a 3/3 colorless Wurm artifact creature token with deathtouch and a 3/3 colorless Wurm artifact creature token with lifelink onto the battlefield.

6/6

I think this card is just begging to be abused in a Welder Trix sort of deck, and at first I thought I'd run a control/sphere shell, but then I realized that that was the wrong direction to go with the Engine.

I then scrolled back through some old decklists and found 2-card Monte (thank you Matt Elias). Here's what I came up with after some thought experiments and a bit of testing:

Combo Engine

Land (20):
4 Mishra’s Workshop
4 Ancient Tomb
7 Mountain
4 Bazaar Of Baghdad
1 Tolarian Academy

Artifact Creatures (7):
3 Wurmcoil Engine
4 Painter’s Servant

Artifacts (22):
1 Black Lotus
1 Lotus Petal
5 Moxen
1 Mana Crypt
1 Sol Ring
1 Mana Vault
1 Memory Jar
4 Grindstone
4 Serum Powder
3 Helm Of Obedience

Creatures (4):
4 Goblin Welder

Enchantments (4):
4 Leyline Of The Void

Instants (3):
3 Red Elemental Blast

SB
4 Shattering Spree
1 Red Elemental Blast
3 Pyroblast
2 Tormod’s Crypt
1 Trinisphere
4 Leyline Of Sanctity

Now the SB is not hard and fast, but I'm looking for it to address a couple decks/cards.

1. TPS (Leyline of Sanctity + REB effects is the game plan there to protect the Leyline)
2. Extra Dredge Stuff
3. Tezz (REB effects)
4. MUD (Sprees)
5. Null Rod (Sprees)

Let me explain a bit about the deck concept. This is basically 2-Card Monte sans tutors and with Bazaar + MD REB. Why might this be good you ask? Well, the big problem that 2-Card had was that it would lose to Fish on the back of Null Rod + Counters. How do we sold this minor problem?

1. Welder (Counters)
2. Wurmcoil Engine (Rod)

I still think Fish is favored, but post SB you get more REBs and hopefully that'll help ya get there. I don't expect a ton of Fish in the new meta so this deck really isn't designed to beat it.

Where the Engine really shines is MUD. Against MUD (Rod or no Rod) you can now completely play around Smokestack by creating an extra creature each turn with an active Welder. Or you can just hardcast the fatty Wurm and ride it to victory. A problem card is still Duplicant, but hopefully you'll have an active Welder out to negate possible dups.

I'm not really sure that this deck belongs even in the tier 2 of decks yet, but it certainly an exciting idea to mess around with in my view. Thoughts, as always, would be appreciated.
