This vintage-legal engine relies on the synergy between Fastbond and Crucible of Worlds to completely bypass the normal limitations of land drops, allowing you to replay the very same land over and over again from your graveyard. Need for Speed acts as the crucial outlet for this loop, turning your lands into expendable resources by sacrificing them to its active ability so they can immediately be fetched back out. The only catch is Fastbond's life-draining drawback, meaning you'll want a way to mitigate that damage while you generate an endless stream of landfall triggers and mana from your lands entering the battlefield.
