How it works
Activate Harnfel by discarding a nonartifact Lhurgoyf card.
Disa the Restless' first ability triggers, putting the discarded Lhurgoyf from your graveyard onto the battlefield.
When the Lhurgoyf enters the battlefield, Cloudstone Curio triggers, returning another nontoken nonartifact Lhurgoyf from the battlefield to your hand.
Resolve the Harnfel ability from step 1, causing you to exile the top two cards of your library with the ability to play them until end of turn.
Repeat.
This brilliant loop is fueled by Harnfel, Horn of Bounty (the backside of Birgi, God of Storytelling // Harnfel, Horn of Bounty), which lets you trade away your hand to dig deep into your library. Whenever you discard a nonartifact Lhurgoyf card this way, Disa the Restless immediately pulls it right back out of your graveyard and puts it onto the battlefield. That creature's arrival triggers Cloudstone Curio, allowing you to bounce another nontoken nonartifact Lhurgoyf back to your hand so you can feed it right back into Harnfel. You can repeat this sequence to endlessly cycle your creatures, chewing through your entire library while generating infinite enters-the-battlefield and leaves-the-battlefield triggers.
