Secrets of Strixhaven Commander

Artifact

{T}: Add {R}.
As this artifact enters, you may have it become a copy of any creature on the battlefield until end of turn, except it has haste.

Cursed Mirror

Try to play commander on turn 3...and then keep replaying it until you're rich.

Cloning My Sphinx to Make Rocks

Felt like marking this in my collection at least. This is my most powerful and explosive budget deck. It runs only 3 creatures besides the commander, a whole lot of mana rocks, a whole 
lot of draw, and a funny amount of ways to make 1/1 gobbos deal a lot more damage.

Reign of Dragons Foundations Preconstructed Commander Deck

This is the actual decklist that I own.
Draft the Commanders first 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 14 for 60 card decks and 6 or 7 packs of 14 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
