The deck is good, but I totally lost it at the wikiHow.

:D

Metallic Mimic seems worth testing over Adaptive Automaton since it makes your dudes less susceptible to spot removal on a lord.

Yeah, you're right, quakenbake. The Mimic's price has been falling precipitously recently, though, and I'm reluctant to buy it until it looks like its value has bottomed out.

I like Naya Humans, casting Lightning Berserker for the Dash to keep triggering Champion of the Parish and Thalia's Lieutenant turn after turn.

It's a decent enough synergy, Darsul, but it doesn't really seem necessary; Champion and Lieutenant are powerful enough just be being in a deck full of Humans without trying to find extra ways to trigger them. I feel like the advantage of would be Burning-Tree Emissary/Lightning Mauler, which can can result in some really explosive starts, plus the access to burn spells but I can't really risk having many non-creature spells in my deck because Ancient Ziggurat makes up a big part of my mana-base for budget reasons.

Collected Company seems good in this deck

It's way too expensive, unfortunately, both in it's own right and because it would require me to rebuild the mana-base without Ancient Ziggurat.

Path to Exile is far too good to only run one of. I'd cut two Thraben Inspector and a Mayor of Avabruck and just run the full play set of paths.

Thanks for the suggestion, krestofu; I initially only put 1 Path in there because I only owned 1 and just didn't want to spend the money on buying more, but you've made me re-evaluate that. That being said, I actually don't agree that the full 4 is the correct number - or not in the maindeck, at least - since, between Ancient Ziggurat and Thalia, Guardian of Thraben, it's not always super convenient to cast and there a bunch of decks in Modern against which Path to Exile ends up being somewhere between bad and completely worthless (Ad Nauseum, Living End, Tron, Bogles, Scapeshift for example).
