The major essence of a control deck is to make sure they do not miss out on their land drops to have enough mana to cast their big spells. One way to do this is to have more lands in the deck such as 26 in the number of more or have ‘ramp’ spells in the list. One good example of this is the Standard deck I am sharing today. The deck is Bant Control and was one of the undefeated decks in the recent MTGO Standard League.
