A Dion, Bahamut's Dominant Commander deck is a Knight Typal deck, meaning it's a deck that focuses primarily on one creature type, in this case, Knights
Right now, combing through Magic Online decklists, I see a ton of people playing Search for Azcanta, but thats just one of many important lands that you need to be able to interact with
This means that the card has no cost, which is very important
As a quick primer Unlimited cards have a white border, CE and ICE cards have black borders with pointed corners, beta cards have black borders with 1 mm (standard) corners, and Alpha cards are black bordered with 2 mm (non-standard) corners
This Duskmourn: House of Horror Endless Punishment Commander Deck includes 1 deck of 100 Magic cards (98 nonfoil cards and 2 Traditional Foil Borderless Legendary cards), 10 Archenemy cards, a 2-card Collector Booster Sample Pack (contains 1 Traditional Foil or nonfoil alt-border card of rarity Rare or higher and 1 Traditional Foil Uncommon card), 10 double-sided tokens, 1 deck box (can hold 100 sleeved cards), 1 Life Wheel, 1 strategy insert, and 1 reference card.
I consider Bonesplitter to be a staple for Pauper Cubes, and a very nice addition to most Cubes with a heavy focus on combat
