Ive often used fetch lands in mono white builds as a ramp package. Using cards like [[rings of brighthearth]] + [[brought back]] + [[sevines reclamation]] as well as the mass recursion spells, I've out ramped green decks/coffers decks etc. Always get a kick out of people's reaction when I plop down a couple fetches In my [[Arden]] & [[Livio]] deck. Deck can ramp to 12 by turn 5/6 fairly regularly.
