mtg streets of new capenna commander decks Deck - Bedecked Brokers fifteen other new MTG Streets of New Capenna

Further Upgrades The first cards I'd pick up to further juice up the deck would be untapped mana-fixing lands: Watery Grave, Shipwreck Marsh, Underground River, Morphic Pool, Darkslick Shores, Polluted Delta, Sunken Ruins, Undercity Sewers, Urborg, Tomb of Yawgmoth and then maybe a couple more Island / Swamp fetches

Warner: Cautiously optimistic

Also, many of them have Enrage, which will provide a boon to you when they take damage

And since you can tap your commander to untap Leyline Dowser, that can happen whenever your commander doesn't attack for the turn (or do anything else that requires tapping)

But when the card works, you get like a 10-for-1 because you cast two spells and obliterate opposing boards
