Prairie Stream - Commander: Modern Horizons 3 (Rare) [M3C-365]

Prairie Stream is a dual land that produces either white or blue mana, entering tapped unless you control two or more basic lands. This makes it a solid choice for decks that include both colours and have a focus on basic land synergy. It provides reliable mana fixing, particularly in two-colour strategies, but its entry condition may slow down play in the early game if you lack basic lands.
