Enchantments in your graveyard will have escape, giving your some welcome recursion
Sidequest: Raise a Chocobo / Black Chocobo Rating: 5/10 The opportunity cost of Sidequest: Raise a Chocobo is extremely low, since you get a 2/2 for 2 mana right off the bat
The front side of this Commander is fine, it generates mana for noncreature spells, but the backside is where the main strategy reveals itself
The four decks coming back are "Devour for Power" (helmed by The Mimeoplasm), "Built from Scratch" (the Daretti, Scrap Savant deck), "Wade into Battle" (with Kalemne, Disciple of Iroas leading the charge), and "Breed Lethality" (with everyone's favorite proliferator, Atraxa, Praetors' Voice)
You can create pretty consistent scenarios where you play a room card and unlock the other door: Victor, Valgavoth's Seneschal lets you surveil 2 while your opponents discard a card
A good chunk of these cards were basic lands, usually 30, with around 25 common cards, some uncommons, and rares mixed in between
