Birgi, God of Storytelling // Harnfel, Horn of Bounty + Sensei's Divining Top + Armor Wars

Birgi, God of Storytelling // Harnfel, Horn of Bounty

Sensei's Divining Top

Armor Wars

How it works

1. Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
2. Activate Harnfel by discarding a card, exiling the top two cards of your library and allowing you to cast them this turn.
3. Cast Sensei's Divining Top from exile by paying 0.
4. Repeat.

This intricate engine feeds on itself by leveraging Harnfel, Horn of Bounty—the back face of Birgi, God of Storytelling—to burn through your deck with Sensei's Divining Top. By tapping Sensei's Divining Top to draw a card and place it back on your library, you set up the fodder needed to fuel Harnfel, Horn of Bounty's discard ability, which exiles the top cards of your library so you can replay Sensei's Divining Top from exile for zero mana. Meanwhile, the cost-reduction passive from Armor Wars's second chapter (and any incidental card draw from its first) helps facilitate casting your artifacts, turning an innocent top-spinning loop into a relentless cycle of self-discard and draw triggers.
