Thank you for pointing out that info. I have an enchantment deck which has a lot of cards based on the "aura" keyword. I might be able to improve it now. Thanks!

You're right. Empyrial Armor is an aura. I thought the subtype "aura" was required for an enchantment to be an aura. All enchantments which have the keyword "enchant" and are attached to a target.

Without many chances to draw extra cards and keep your hand filled, this card relies on the player not playing cards. Since this deck has a low average CMC and most cards will flood from the player's hand, I'm not sure if this 3 CMC card is the best. On turn 3 or 4, you might only have 3 or 4 cards in hand. For 3 mana, better options might exist.

The new Karn, Scion of Urza from Dominaria will fit SUPER well in here. It's best used as a card draw engine, but it's "ultimate" can also work wonders here.

In order to make this modern legal, how would you replace Enlightened Tutor?

This deck is a bit... inconsistent. You have a lot of different cards which look and act similar, but that's it. This deck will not play the same way two times in a row very often, because you have a lot of 1-ofs. If you want to improve the win-rate of this deck, either make everything a 1-of, add a bunch more cards, and pick a commander or remove all of the worst cards and add more copies of the best cards. If your primary goal is the flavor of golems and the ability to surprise your opponent with new cards every turn, good job!

Since you are playing no auras, Kor Spiritdancer is nothing but a 0/2 for 2. Consider swapping Mask of Law and Grace for an aura with totem armor like, Hyena Umbra. This will keep the creature alive after one removal spell, meaning your opponent will need to use 2 spells to kill this creature. Empyrial Armor could be replaced by Aqueous Form, Archery Training, Curiosity, Daily Regimen, or anything that's actually an aura. Authority of the Consuls is a great non-aura card which fits with the control aspect of Cataclysm.

If you're really worried about black spells, look at Black Scarab.

Enlightened Tutor is pricey, but it can help you grab a permanent of a type you don't have before playing Cataclysm. It's possibly the best tutor for this deck.

Ornithopter would be both a blocker until you draw Ensoul and a way to meat Certarch's aratifact presence requirement to slow down your opponent.

Blinding Drone costs 1 more to play but one less to activate and is sorta blue. This card is a tease, because it's colorless but its not an artifact. Vedalken Certarch needs you to have a decent board presence instead of needing mana. If only it counted as an artifact. I'm not sure if these non-artifacts will satiate your needs.

Blasting Station, Geralf's Messenger, and Rite of Consumption. Should these go in the maindeck?

OOH! Ichor Wellspring is a great target for ensouling! Nice pick.

Artifacts are often tappable for some advantage (i.e. Sunset Pyramid). How about Ghostly Touch or Voltaic Key? These would help teach new players the meta of tappable artifacts. Ghostly Touch basically gives an ensouled artifact vigilance. If you add another artifact like Sunset Pyramid which can tap to produce something, then Voltaic Key would be a nice combo. It would let you re-use other artifacts. It's cheap CMC makes it playable and ensoulable early.

If only Sol Ring was a little cheaper. With a larger budget, Sol Ring and Voltaic Key make nice mana ramping. Imagine this: Ensoul Sol Ring and give it Ghostly Touch. Attack with it, then untap it. At the end of the opponent's turn, use Sol Ring for Sunset Pyramid's ability (or another spell/ability). $10 decks are hard to build!

The deck looks like a great teaching tool to me. It shows that some bombs are combos, which throws a little wrench in the mind of anyone recently taught the BREAD analogy.

Due to the super low mana curve, mana ramping is very unnecessary. Which other cheap artifacts could replace the Compass or the Lens?

Add 8 Chancellor of Dross. If you're extremely lucky, your opening hand will be an instant win with 7 of this vampire in it.

Brawl seems like an alternative option for players who like to stay fresh by playing with new sets and like the idea of commander. People who can't build a standard deck that wins prizes at events might like this more luck-of-the-draw style singleton format. Brawl could make these people more interested in attending events and in buying new packs. Is this one of the best ways to play Magic? No. Does it have a place? Yes. Does Vintage have a place in Magic? Yes. Do many people play Vintage? No.

I personally don't like Brawl, because I'm a modern and commander guy. I like having more options and more time to hone decks.

Steady Progress and Inexorable Tide are nice ways to increase your stacks of counters. Contagion Engine and Contagion Clasp are two artifacts which can provide proliferation for 4 mana once a turn.

Nissa, Voice of Zendikar can drop +1/+1s on your entire army, but only once or twice unless you proliferate her.

After Animar has 3 +1/+1 counters, the only creature spells gaining from added counters are the 4 spells with X in their costs. Those spells are GREAT which benefit greatly from a big fat Animar, but Ooze Flux could be a nice way to trade counters (and mana) for a larger army. It will keep your overall board power at the same level while increasing the amount of creatures on your side of the field.

Another even better addition is Scavenging Ooze. If your creatures ever die, this will let you turn their corpses into life and more +1/+1 counters.

If only black was an option... Varolz, the Scar-Striped.

Picking basic artifacts over free artifact creatures like Thopters helps slowdown removal while you're building your forces, but you could consider adding these to the sideboard. If the player learns that the opponent has few to no removal in the first match-up, then they could add Thopters in the second and third, or vice-versa. They could bait the removal out of the sideboard with the Thopters in the first round, then swap them out for artifacts when they opponent's deck has added removal in the later games.

Centaurs are one of the best tokens due to their strength. Add a few more of them.

This deck is 5 years old. Many great spells have been added to our magical toy boxes since 2013. What modern changes could be made to this fun deck?
