Chaos Orb breaks the rules by literally making contact with other cards, then taking them out of the battlefield in the process
Unlike some of the other cards in the series, the Sword of Forge and Frontier manages to be a solid artifact able to play two top-deck cards as well as a land card when successfully attacking, it's no wonder that this blade requires a hefty chunk of change to obtain
It doesnt quite generate the same usefulness for Blue as Blossoming Defense did for Green decks in the last Standard cycle, but hexproof allows this card to double as an effective one-drop counterspell against removal
The Map arrives turn one, can be fetched with Urza's Saga, taps with two to sacrifice, and then grabs any land, not just basics
The Balrog, Durins Bane This card scales quite nicely depending on the power level of your Commander deck
