Syndicate Trafficker really does not do well with this deck. I switched it for Underhanded Designs an yahenni, because i preffer to use the mana to drain the oponent than use it to pump out the syndicate. besides in battles with zombies there is not a good point to swing with the syndicate anyway because it will hit only a zombie token. I've not really hit with it... so the real value of it is to sacrifice the servos and yahenni does it for free. This deck really is to drain the oponnent to give you time to get the win condition. (marionetter, westvale flipped, or in my case Voldaren Pariah flipped).

If you decide the deck isn't performing how you want it to, what about making the few tweaks that turn it into something that resembles Sam Black's Abzan Token deck?

I played against an Abzan list this weekend on MTGO. I like Cryptolith Rite. It would certainly help with the mana problems I kept seeming to run into. The deck also needs card draw. Scrying just isn't enough. Not when Marvel and UR Control can Glimmer of Genius or Pull from Tomorrow, or even just cycle.

have you thought of Servo Exhibition or Weaponcraft Enthusiast

I was running Exhibition, but there are so many 2-drops that are more important than creating 2 servos. I have seen lists with Enthusiast, and they also tend to include Panharmonicon. I can't fit both in the current version of this deck, but I might try that particular variation later.

Dang this is like the exact same deck i put together pre-AHK. I love it and gl w/ it!

ok, going absan only for the mana is not entirely good... since everything is mana based at 1, 2 or 3 i would use those 2 slot for Midnight Oil because in his mana slot you mush have no cards in hand or have 2 turns to do get there. and there you would solve the mana problem by drawing one more card every turn and scrying.

weaponcraft does not need phanharmonicon when you have anointed procession, he will enter the game and put 4 tokens, as well as servo exibition... but i would use sram expertise to get a 2 for one and 6 servos out of it if procession is in play.

I've just built this deck and really like it! Do you think Gideon, Ally of Zendikar would fit in this deck? I feel like he'd be great but I don't want to cut anything.

Yes, Gideon should be in this deck. If I could afford him, he would be in the Marionette Master slot.

How you feel about Liliana death's majesty maybe instead of a marionette

M&M is a finisher/wincon. Liliana would not be a good alternative, IMO.

What do you prefer to sub out for scrapheap and gonti Feel like scrapheap works well for sure and gonti is more situational

Against spot removal, +3 Scrapheap/-3 Trafficker, or -2 Trafficker/-1 Enthusiast. It's too easy to tap out and not have the activation cost to make Trafficker indestructible. Gonti comes in for Pariah against control usually.
