Here’s a new fun deck, away from the Mechaz0r! archetype.
Use absurd amounts of ramp to play Deceptib0t and Echo Deliverant early enough to do their thing.
Also have a plan B with Lady Locke and Nasty Walls® (also named the @snowshot)
Flawless Reflection as an end game joker too.
Edited with Aspect of Shim’Zar as so cleverly highlighted by @phoinexflame
Why no Shimzar for the combo with Deceptib0t?
@rhacker93 built an Echo Deliverant / Deceptib0t deck for his patreons. Not sure if he already posted that deck publicly though.
I actually built a similar deck, and it truly is hilarious (while also being a hard-counter to Xor) when it works (and it usually does, except Vet exists).
Flawless reflection is pretty genius in being a great target for the Mechs, and works as an additional win-con with a lot of things. I personally would like to throw in Zuraels, and 1x Omega to revive everything that does get removed 
Any thoughts on adding Thunderhorn/Sister to increase consistency?
Right about Zurael! I have one and I was thinking of removing an Aspect of the Mountains to include the wonder chicken. You can also remove one Flawless Reflection too.
Hearth Sister could also be a great addition, but I need to play the deck more to decide where she could fit.
Shootout to @deathsadvocate for his “Ghost in the Shell” deck. Did I mention it’s my favorite anime?
In this sequel we have Circulus & Frigid Corona for draw, Ilena and her fist for pinpoint removal, AOE with Frostburn.
Use good positioning and improvise your best burst damage finisher out of Spirit of the Wild and either Ghost Seraphim (7 mana), Cryonic Potential (8 mana), or Mechaz0r! itself.
Bump. Added some more decks to unfinalized and made some small edits to stuff
Just add spelljammer to everything and Mech decks will work.
yo have you considered aspect of drake? not sure if you need it, but it’s practically mass-flight for vanar. imagine 16 damage flapping down on that rando on the ladder
Interesting. I will think about it.
I’ve been trying my hand at budget decks, and this month was working with Mechs in a couple of factions. They’re mostly minor variations on decks already posted above, not quite as competitive but still good enough to win games. More importantly, they’re fun to play and have some interesting gimmicks.
Lyonar Mirror Mechs
Based off of Boronian’s suggestion above. This is the first deck in which I’ve felt that Mirrorim actually earns its slot. On its own it turns Replicant into a discount Endless Hunt, and combined with Lifestream it copies Mechaz0r directly into your action bar for great value.
Value Unbirth
Did you post them on duelspot too? 
They look like fun decks!
Yeah, I should have mentioned that I gave these writeups on Duelspot: Lyonar, Abyssian.
They really are fun to play! In particular, Metaltooth is such a sweet card and makes me nostalgic for pre-nerf Tiger.

Also z0r is a cool minion that cycles, and happens to be another 2 drop, so it doesn’t really get too much in the way of the cards you want to play in a turn. It could potentially give you a really useful mech (such as Oakenheart for non-lyo, and Seismoid for late-game hand dump) and I think it could replace jammer in slower mech decks. It does have a problem that it doesn’t proc Metaltooth, and doesn’t have other mech synergies, although the turn 2 Mechaz0r without dumping 5 mechs out is pretty sweet.
Thoughts?
Z0r is funny and early card draw is always nice.
Its non-Mech status means that he won’t be spawned by Deceptib0t (good for tutor focus!), advantageous compared to Replicant for early card draw in that situation… But if it gives you a crappy Mech, then it’s sad.
Z0r was a better option for Mech decks before the Vanguard expansion. With the original pool of mechs, its dying wish would usually get you a progress mech and had a not insignificant chance of pulling Mechaz0r itself, with Rexx as the only booby prize. After Vanguard, the pool of mechs has more than doubled, and fewer than half of them are progression mechs. This makes Z0r too high-variance to be played seriously anywhere.
If you’re looking to meme, though, one place I could see Z0r working is for Maehv, where it supplies card-neutral sacrifice fodder. Something like this:
Maehv MechaXor
This is worse than a normal Xor deck, and those aren’t exactly high-tier to begin with, but it at least has the potential for some funny interactions.

I get the feeling this thread should just die, it takes a bit of effort to test new decks, and I’m a bit too lazy to keep editing the post to reflect the ideas don’t really work so well, but are viable nonetheless in gold.
Bump.
I put some new material on Duelspot recently, including this post on DECEPTIB0T combo decks. It includes a few new lists, forcing DECEPTIB0T into previously untouched factions:
I don’t have too much to say about these; they’re mostly just piles of midrange goodstuff with the DB0T package thrown in, and haven’t undergone any extensive playtesting. The Abyssian list might be better with Cassyva and Nethermeld.
I also discovered that sadly, the Deathwatch keyword is not supported by S.I.L.V.E.R. Checking its wiki page after the fact, I see that neither is Zeal or Dying Wish, which is too bad. What confuses me, however, is that it claims that Rebirth is supported, even though there’s no way of granting a minion Rebirth. If anyone has any insight on this it would be appreciated.
