Spinerock Knoll is relatively easy to pull off in Commander and can provide you with extra cards (sort of), and Mines of Moria let you bank mana for a rainy day
You use Wrenns -3 ability to make a 5/5, use that 5/5 to crew the Chariot, and then use the Chariots ability to make another 5/5 during combat
While we dont know what each of these themes do mechanically, Wizards has named all ten themes youll find in Dominaria Uniteds Jumpstart packs: Dominaria Uniteds Commander Decks As with all Standard sets these days, Dominaria United is coming with a collection of Commander preconstructed decks
Note that other than the colorless mana spent, there are no other costs here like tapping or once per turn or only on your turn
Miracle is a keyword for an alternate cost that can only be used when: The card is the first that youve drawn that turn Only immediately after you draw that card
Brilliant for getting the best card-draw, STE, or ETB or synergy or win-con back
