The cycle lands are amazing. They looks like crap (and it often feels bad to be playing them tapped to be fair), but tossing them for a card when you have extra mana is just so much value. LFTL might be the best combo piece with them for obvious reasons, especially if you have a couple early. But even in a random deck with no synergies, I can't count how many games they have saved from screw/flood. These are innocuous cards that just make for better games of Magic IMO.
