As prior AF, I can't even be mad at the name of this deck LoL

If you can get your hands on any of the Eldrazi Titans from Rise of the Eldrazi set, get one into the deck. You can discard it to Mind over Matter to shuffle the 'yard back into your deck, basically reloading your deck-drawing machine gun.
Happy Combos !

I have a Niv-Mizzet deck posted on here as well. It plays quite differently, but I've been able to trigger infinite combos as early as turn 7

If you're about card advantage then Ob Nixilis ought to be here as well, I think.

A few copies of Heart of Kiran in place of the Smuggler's Copter, since the ol' Looter Scooter was hit with the ban-hammer.
Or for a budget option, Untethered Express.

Reckless* Bushwhacker

Goblin Bushwhacker. Gives everything +1/+0 and haste until EOT ... Id cut the Augmenteers and the Dreadnoughts for a set of Bushwackers to better the chances of the combo going off. I'm actually interested in proxying the deck (with Bushwackers) to see if it'd work

So talking to a friend, he pointed out that you'd have to find a way to give the 2/2s haste, otherwise they can't tap for the additional mana from the Rite. I apologize for not catching that before.

Even better. With the Rite, every 2/2 Servo taps for another 2/2 Servo, creating an infinite loop of 2/2s.

Not sure why you wouldn't include one or two Animation Module. With the Mimic naming Servos, you create a loop of creating 2/2 Servos much quicker than paying 3W for the Trinketeer.

Holy schmoly .. I like this better than the list with the hydras.

Personally, I would run the Cryptbreakers and Relentless Dead over Asylum Visitor in the main.
Reason being Visitor punishes you if either player has no hand, whereas Priest rewards you.
Also, I would drop the Indulgent Aristocrat in favor of Lightning Axe as an answer to Kalitas or Avacyn.

If you're looking to build a mill deck in the current standard rotation, you should take a hard look at the Investigate mechanic from SOI

Have you looked into Veteran Cathar ?

Thing actually flips into a 7/8, my apologies.

With so many instants and sorceries, Thing in the Ice should be in here. A 2 drop that flips from 0/4 to 9/7 and wipes the board it could easily get there

Just one Kalitas can throw off Tokens. 3x Kalitas in the main is a pain in the backside. Tokens would want to pump Hangarbacks when possible. Drop Kalitas before Hangarback gets too big, and when it dies, it becomes exiled and the Thopters are nullified, further throwing off the Token's strategy to fill the board. Secondly, Tokens plays mostly creatures at or under 3 toughness, all of which Kalitas exiles. Third, you could drop Gideon, -4 for emblem, and next turn Drop a 4/5 Kalitas than can, turn after, take down Nissa or Gideon your opponent plays, and you gain the 4 life. Even if you take a beating early, Kalitas can bring you back up and over 20 in no time. Even if you put in card draw like Read the Bones, Kalitas effectively makes the self-damage moot. The only way Tokens can get around Kalitas is either the one or two Stasis Snare in the main or the Quarantine Field from sideboard, or they have to get real creative and play Gideon, +1 to make him a creature, and play Dromoka's command, target Gideon to give +1/+1 and fight it. Otherwise, he's there to stay. I think by now you get my point.
Relentless Dead is only a notch below Kalitas. Even if it dies to combat damage, the BW player can pay 1 Swamp to return it to their hand, and it's only a BB on the next turn. And it has Menace.
I've also seen Avacyn in BW to counter the Avacyns run by Tokens.

Hallowed Moonlight (1W/Instant) is an easy answer against Secure the Wastes or Hangarback Walker.
Been playing Steve Rubin's GW Tokens against different BW control lists and haven't fared too well. BW Control has the upper hand if you keep the board clear and force Tokens to play reactively or defensive.
And have you tried any testing against 4 Color Rites ?

Replace the Guides with Zada. It won't throw off your curve and she'll be a boon in this kind'a deck. Drop your lands down a few to 18 or 19 and replace them with Titan's Strength or another cheap buff spell.

Definitely. Drop the Genesis Hydras and move the Managorgers to main. Nothing embodies a Hydra / Counter deck theme more than a Managorger

If you like lifelink, Shambling Vent isn't a bad choice. It'll give you flexibility with mana early in the game and steal some extra life early if you can get it.
