So how do you pick which ones to run

Fetchlands like Misty Rainforest are great ways to reset the top of your library to get a fresh look with The Fourth Doctor, but Id also recommend trying out cards like Bant Panorama and Shire Terrace which enter the battlefield untapped and tap for colorless mana in the early-game, and then you can cash in for a basic land and shuffle your library later when you need it

Combine her with a Vorinclex Voice of Hunger and a Doubling Season, and you could be taking opponents of the game super-fast
