The combo is built around the non-green nephilim, Yore-Tiller Nephilim, Medomai the Ageless, and Viscera Seer (or any creature with a sacrifice a creature ability)
The Doctor Who Masters of Evil Commander Deck includes 1 ready-to-play Blue-Black-Red deck of 100 Magic cards (2 Traditional Foil Legendary cards, 98 nonfoil cards), 10 Planechase cards, 1 six-sided planar die, a Collector Booster Sample Pack (contains 2 Traditional Foil or nonfoil special treatment cards, with 1 Common or Uncommon and 1 card of rarity Rare or higher), 1 foil-etched Display Commander (a thick cardstock copy of the commander card with foil etched into the card's border and art), 10 double-sided tokens, 1 deck box (can hold 100 sleeved cards), 1 Life Wheel, 1 strategy insert, and 1 reference card
Grenzo could be your commander for this, too, if you like more aggressive commanders
Ive seen a few stores with Secret Lair goods and your best bet are larger stores that buy cards from customers and carry a lot of Magic products
