Xbox 360 Cube

Sokka and His Friends Kill You

I made this deck because of all the cool avatar cards.
I can't wait to bring this legal deck to commander night!

The Quintessential Avatar Deck

Narset is Punches You in the Face

This deck is not good...but it has all avatar cards...not counting the lands...

A2ula: Just ATLA Cards

Not sure I made a good version of this deck...but it is a version of this deck

Here are is the real list of commanders for the cube!

Real Spellslinger Commander Cube Commanders

This is the actual decklist that I own.
Draft the Commanders 1st from a special pool (in the sideboard) with 4 packs of 10 or 12.
Each commander has partner. If you want to use one of the companions, you can do that as well if you abide by the companion rules and color identity rules. For Umori specifically, you may still have creatures as your commanders as long as the rest of the deck follows its companion rules.
I suggest choosing your commanders (and sometimes a companion) before you've drafted from the main pool. 
Each player automatically gets a command tower and an arcane signet.
Before drafting, players can decide if they want to draft 60 card commander decks or full-sized 100 card decks.
Draft 4 packs of 15 for 60 card decks and 6 or 7 packs of 15 for 100 card decks.
Color Identity does not matter when it comes to lands.
Draft Archetypes:
Reanimator
Cast spell, get value
Freecasting
Theft
Copying spells
Value for targeting your own creatures

Commanders for drafting the spellslinger budget commander cube

I realized that the main problem with the last iteration of this Cube was it included white. That pillar was taking a lot of space that could have gone to red and other colors. It seemed to dillute the experience so I made another one without such a useless color.

You may bypass the color identity restrictions if absolutely needed.

Spellslinger Commander Budget Cube

The rules are, each player automatically gets an arcane signet and a command tower before drafting even begins.  Also, you can break commander color identity rules if you have to.

Commander Cube

Budget Artifact Cube

Seems like you have to pick 2 color archetypes...so you mix the unlimited pool...It's an interesting question of do you get the unique card that buffs your archetype or do you go with the one's you've already drafted.

I threw in a small meld subtheme here. The melds are in the sideboard. I maybe put in a few too many extra combats...but yolo
