Chulane triggers, causing you to draw a card and put Guildless Commons from your hand onto the battlefield.
Guildless Commons enters the battlefield, triggering itself and Nissa.
Resolve the Nissa trigger, adding .
Resolve the Guildless Commons trigger, returning it from the battlefield to your hand.
Shrieking Drake enters the battlefield, returning itself from the battlefield to your hand.
Repeat.
This clever loop centers on the self-correcting synergy between Shrieking Drake and Guildless Commons, which constantly bounce each other back to your hand to endlessly re-trigger your battlefield effects. Chulane, Teller of Tales accelerates this engine by turning every creature cast into an extra card drawn and an immediate land drop, which seamlessly puts Guildless Commons right back into play. Meanwhile, Nissa, Resurgent Animist converts that revolving door of land drops into an endless supply of colored mana and triggered ability searches to dig through your deck. Together, these four pieces transform a simple one-mana flyer into an unstoppable storm and draw engine.
