The only reason people win tournaments with these garbage Legacy Land Destruction decks (read: Merfolk) is because everyone else in the room is playing a deck with poorly constructed mana. When your two ways to win the game are 1) being on the play in the mirror, or 2) hoping your opponent constructed their deck incorrectly, it’s not a very good recipe for success. Although, the latter seems to be a pretty safe bet in most Legacy tournaments these days.
