This vintage combo turns your graveyard into a relentless staging ground for your land drops, fueled by Fastbond removing any restrictions on how many lands you can play each turn. Ramunap Excavator steps in to bridge the gap, allowing you to continually reach back into the graveyard to replay whatever you've sent there. Finally, Sylvan Safekeeper gives you a very active way to cycle those lands into the graveyard while protecting your board, creating a seamless loop that generates infinite landfall triggers and uses your lands' mana generation over and over again.
