i replaced a basic land with a deserted beach in my deck and now its saying there is black in the deck and cant be used. im using choco seeker of paradise (G,W,U) as my commander and i cant use the deck now. it doesnt even show i have black in the deck when i check the deck details. and even if i take deserted beach out it still says it has black in the deck. ive even tried removing all the cards from the deck and it still says its black in the deck.
