How it works
If you have six or more cards in hand, activate Harnfel by discarding a card.
Repeat step 1 until you have five or fewer cards in hand.
At the beginning of your end step, The Ten Rings triggers, causing you to draw cards until you have ten cards in your hand.
Lyla triggers for each card drawn, putting that many +1/+1 counters on Sage of Hours.
Activate Sage of Hours by removing all +1/+1 counters from it, causing you to take at least one extra turn after this one.
Repeat each turn.
This engine turns your end step into an infinite loop of extra turns by cycling cards away and drawing them right back. Harnfel, Horn of Bounty lets you rapidly discard your hand to dig through your library, ensuring your hand count drops low enough for The Ten Rings to trigger at the beginning of your end step and draw you a flood of cards. Every single one of those card draws triggers Lyla, Holographic Assistant to pile +1/+1 counters onto Sage of Hours. Once you've amassed enough counters, you can cash them in to take extra turns, all while Birgi, God of Storytelling helps fuel your mana along the way.
