I will always remember the time I kept a 2 lander with a ramp at 3 mana in a landfall deck with 40-42 lands. Never drew a land in the 8-10 turns of the game. Endend up getting my third land when someone introduced the initiative and I got it by attackign with a creature given to me with Jon Irenicus ability. Ended the game with like 15 lands in play thanks to ramp spells, but didn't drew a single land in the game.
