Sage of Hours + Sunbond + Celestial Mantle

Sage of Hours

Sunbond

Celestial Mantle

How it works

1. Deal combat damage to an opponent using the creature that has Celestial Mantle attached.
2. Celestial Mantle triggers, doubling your life total.
3. Sage of Hours triggers, putting a number of +1/+1 counters on it equal to the life you gained.
4. Activate Sage of Hours by removing all +1/+1 counters from it, causing you to take at least one extra turn after this one.
5. Repeat each turn.
