Mana flood

Mana flood refers to the condition of having too many lands (either in play or in hand) and not enough spells. Mana flood can be the result of an opening hand with too many lands, several consecutive land draws, or a combination of the two. A hand with too many lands, for example five, is often best mulliganed for a better distribution, and some casual variants of the mulligan are more forgiving of such draws. However, a deck which consistently experiences mana flood may need to run fewer lands. Even in a deck with a good mana curve, poor shuffling can result in clusters of lands in the deck, which can cause mana flood when the player hits them.
