Sage of Hours + Master Biomancer + Delina, Wild Mage

Sage of Hours

Master Biomancer

Delina, Wild Mage

How it works

1. Declare Delina as an attacker.
2. Delina triggers, creating at least one token copy of Sage of Hours that enters the battlefield with at least five +1/+1 counters due to Master Biomancer.
3. Activate the Sage of Hours token by removing all +1/+1 counters from it, causing you to take at least one extra turn after this one.
4. Repeat each turn.

This clever loop relies on Delina, Wild Mage generating attacking token copies of Sage of Hours when she swings. Because Master Biomancer boasts a hefty power, every single one of those incoming Sage of Hours tokens immediately enters the battlefield pre-loaded with five or more +1/+1 counters. This lets you instantly cash in those counters using the Sage of Hours token's own ability, taking extra turns back-to-back until your opponents are completely locked out of the game.
