This clever loop uses Rakdos, the Muscle as a sacrifice outlet that fuels your hand by exiling your library, while Haunted Crossroads conveniently recycles your threats back to the top of your deck.

Meanwhile, Phantom Train acts as the engine's catalyst, converting those recycled creatures into +1/+1 counters and turning your sacrifice loops into an unstoppable cascade of triggers.
