Okay, this one's going to be a bit tricky, since there aren't too many land-generating cards in the game, and you have to have 36 spells (so you can't cherry-pick the ones you want). It also may take a while since you'll need to unlock the cards.
The main ones are in green and white. The trick is getting them into your hand first so you can get them out.Cultivate (2G) - Search your library for two land, put one on the battlefield and one in your hand
Elvish Pioneer (G) - Put a basic land from your hand onto the battlefield tapped
Satyr Wayfinder (1G) - Reveal the top four cards of library, put a land from them in your hand and the rest in your graveyard
Traveler's Amulet (1) - Pay 1 and sacrifice: search for a land and put it in your hand. (Good for getting a color)
Kor Cartographer (3W) - Search your library for a Plains and put it in play tapped (Great, but expensive. Nice as a 4th turn card.)
I filled the rest with Scry cards, since I could look at the next card and tell if it would help, or mill it.
After you're finished, go to Practice Duel and run through 4 turns. It took me quite a few tries, but the main problem is that there just aren't many good cards for grabbing land.
Edit: It may also help (a lot) by playing with someone who can bounce your creatures back into your hand. That way you can recast one of the creatures to move a land to the board, especially the Pioneer.
