Sage of Hours + The Ten Rings + Witch-king of Angmar + Lyla, Holographic Assistant

Sage of Hours

The Ten Rings

Witch-king of Angmar

Lyla, Holographic Assistant

How it works

1. If you have six or more cards in hand, activate Witch-king of Angmar by discarding a card.
2. Repeat step 1 until you have five or fewer cards in hand.
3. At the beginning of your end step, The Ten Rings triggers, causing you to draw cards until you have ten cards in your hand.
4. Lyla triggers for each card drawn, putting that many +1/+1 counters on Sage of Hours.
5. Activate Sage of Hours by removing all +1/+1 counters from it, causing you to take at least one extra turn after this one.
6. Repeat each turn.
