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
Commanders that would love to see this equipment in play include Syr Gwyn, Hero of Ashvale, and Bruenor Battlehammer, where their abilities reduce the equip cost of your cards so you can easily reattach them to your Commander
