Lotus Field - needs to be banned
Lotus Field's downside, the requirement of sacrificing two lands, can be negated by cards like Strict Proctor and Blood Sun. Once the lotus field hits the field, destroying the cards that combo to it is no longer useful.
There's really no way to interact or sideboard against the combo, so the card itself should be banned
Lotus Field should be banned. It's so boring to play against. Requires zero skill and takes too long for opponent to win.
