This delightful loop transforms a simple one-mana creature into an engine for endless card draw and mana generation. By casting Shrieking Drake, you trigger Chulane, Teller of Tales to not only draw you a card but also slam Gruul Turf directly onto the battlefield. That bouncing land then triggers Lotus Cobra for a steady stream of mana while picking itself back up to hand, and the Drake's own entry trigger bounces itself right back to your hand so you can cast it all over again.
