This clever loop uses Abaddon the Despoiler to turn your low-cost creatures into lethal engines, provided your opponents have lost enough life to set X to zero. When you cast Shrieking Drake, Abaddon's static ability grants it cascade, instantly pulling the zero-mana Lotus Bloom straight from your library. As the Drake enters the battlefield, its mandatory trigger bounces itself right back to your hand so you can cast it all over again. Meanwhile, sacrificing Lotus Bloom yields the exact blue mana you need to recast the Drake, while Epitaph Golem quietly recycles the Lotus from your graveyard back to the bottom of your library so it can be cascaded into once more.
