4. Deal combat damage with Sage of Hours, triggering its abilities granted by Conclave Sledge-Captain three times, putting three +1/+1 counters on Sage of Hours for each damage it dealt
5. Activate Sage of Hours by removing all +1/+1 counters from it, causing you to take at least three extra turns after this one
6. Repeat during your last extra turn
