Sage of Hours + Master Biomancer + Eldrazi Displacer

Sage of Hours

Master Biomancer

Eldrazi Displacer

How it works

1. Activate Eldazi Displacer by paying 2C, blinking Sage of Hours and causing it to enter the battlefield with five or more +1/+1 counters on it due to Master Biomancer.
2. Activate Sage of Hours by removing all +1/+1 counters from it, causing you to take at least one extra turn after this one.
3. Repeat each turn.

This clever combination locks down the game by chaining infinite turns, fueled entirely by the synergistic interplay between these three permanents. Master Biomancer is the crucial static engine here, ensuring that whenever Eldrazi Displacer blinks Sage of Hours, the Merrow Wizard re-enters the battlefield with five or more +1/+1 counters already waiting on it. From there, you simply cash in those counters using Sage of Hours's activated ability to take an extra turn, untap, and repeat the process indefinitely.
