digimon blackwargreymon card [BT5-069] (Tamer Party Pack -The Beginning-) [Battle o Digimon Rarity Digimon Card Game/【BT-08】NEW HERO]Black War

The other two opponents were playing what was probably a Bracket 2 Hermes, Overseer of Elpis deck and a Ferrafor, Young Yew list that might have been Bracket 3, but that's just a guess on my part

Replacement Commanders is meant to emulate a precon-level deck (though sometimes splurging on a better lands, because a good mana base can make a deck run much smoother)

Steward of the Harvest is the one thats sparked the most conversation, allowing you to turn all your creatures into Strip Mines or Gaea's Cradles, or just normal, humble mana dorks

Outside of that it's not very relevant, but it's a safe bet for dedicated zombie commanders since it can drop down for 1 mana and tap your team for a bunch of cards
