I've had a couple games where a boardwipe would basically win me the game. Being able to play some stuff down, wipe, drain for 4-5 life oftentimes, and play Lurrus to use that big graveyard as another hand is just backbreaking against certain decks. The main worry is getting the right combination of lands.
