Mycosynth Golem

What a great idea, this is superb! A great communal effort!

Sol Ring , Draco

Thanks for the first few cards! In the future try to add a little description as to why the card should be in the deck (even if it seems self explanatory). This will benefit the discussion over the deck in the long run!

Blightsteel Colossus , Palladium Myr , Myr Superion and Plague Myr might be good in this deck.

Goblin Welder - get back the fat stuff to throw it again

Myr Battlesphere - fat thing to throw and chump tokens for Goblin Welder

Mox Opal , Karn Liberated .

my reasons being you will always hit the 3 artifact requirement for the opal so it's good for a mana source. And Karn is just Karn.

Arcbound Lancer when you sac it you can move the counters to other creatures also a solid 7 damage Akroma's Memorial just read the card

I think this a really great project, +1. Also, if you want to, stick in 4 Cloudpost and a Myr Galvanizer

For lands there are urea lands I think Urza's Mine is one and Urza's Power Plant and Urza's Tower

Mishra's Workshop, Mana Crypt - colorless ramp is good when your deck is mono-artifacts.

Ornithopter , Memnite

Mycosynth Lattice Vandalblast

to take the fun out of everyone's day

lattice can make enchantments and things flingable too

sorry, im going to cheat a little and add a two more suggestions (I cant help it Q_Q)

Unwinding Clock for psuedo vigilance on your creatures, reuse tap effects, break Mycosynth Lattice

Vedalken Orrery so that everyone else's turn is your turn, works super well with the clock and lattice

I run a bunch of things like that in my commander deck (tho mine is esper colored)

Polanety this is edh he can't stick in 4 Cloudpost, although adding Glimmerpost Vesuva Thespian's Stage might be able to make it a functional choice anyways.

My own recommendations are the new red legend, kurkesh, Onakke ancient, who doubles your artifact activated abilities which is crazy cool, and Gamble to help you deal with Bosh getting tucked; and if you have artifact recursion, it's practically just a tutor.

Darksteel Collosus is another power-house in combat. also Quicksilver Amulet is good with all of your high mana cost creatures.

Gotta have your tutors (there's 4 for colorless): Planar Portal , Ring of Three Wishes (which you can throw when empty), Kuldotha Forgemaster , Eye of Ugin

xcn Right sorry, I am used to using them in my 12post decks, sorry.

Sword of Light and Shadow - this specific color protection will get your general around most targeted removal spells. It also returns a creature, preferably a high cost artifact creature, back to hand to be used for ammunition.

Sword of Feast and Famine - A lot of decks specializing in commander damage like multiple swords, but these two are the only ones I suggest since your damage comes from shooting ammo. There's a lot of artifact hate in green, so this helps with that not to mention black removal once again. Its ability gives card advantage, which is meh for the cost, but the mana can be really powerful since his ability is too expensive to proc multiple times per turn easily.

Lands that tap for Red:

• Great Furnace - also an artifact (relevant for Mycosynth Golem and Kuldotha Forgemaster )
• Forgotten Cave - you can always cycle it if you don't need anymore red

• Spinerock Knoll - Bosh can make that 7 damage happen fairly easily

• Valakut, the Molten Pinnacle - only add if you have enough Mountains

Etched Champion : will have protection from colored spells.

Steel Overseer : makes your artifact creatures bigger.

This is a really cool idea.

I think its funny how clearly you state 2 suggestions per user and how a lot of people who are posting just completely ignore that.

Grim Lavamancer - You are throwing all of your cards away, so why not use them in your graveyard?

Sneak Attack - this makes your huge CMC cards so much easier to get out.

Ancient Tomb and City of Traitors - they are both very powerful in decks with huge mana costs.

Strip Mine and Wasteland plus Crucible of Worlds - Land destruction plus land return.

Sorry if I had a ton of suggestions, I just love this deck idea and think all of these could help.

I agree with dagan94 every one is cheating on more than 2 suggestions so I'm not going to let that stop it with me sooooo...... Goblin Charbelcher added burn, Hellkite Tyrant insta-win, Thran Dynamo one of the least utilized mana ramps in EDH, Frogmite +Myr Enforcer free creatures, Shivan Gorge land damage, Voltaic Key untap much?, Sculpting Steel is literally ANY ARTIFACT!!!, Darksteel Forge cause fuck you that's why, Loxodon Warhammer cause what's better than bosh bashing? Bosh bashing and you gaining that much life, ok that's 5 times my limit so here is your job now: pick the best 2 and use them as my suggestions ;-) good luck
