Glorious Protector + Icewind Stalwart + Teleportation Circle

Glorious Protector

Icewind Stalwart

Teleportation Circle

How it works

1. At the beginning of your end step, Teleportation Circle triggers, blinking Glorious Protector.
2. Glorious Protector leaves and enters the battlefield, returning Icewind Stalwart from exile to the battlefield, and triggering both Icewind Stalwart and Glorious Protector's enters-the-battlefield abilities.
3. Resolve the Glorious Protector trigger, exiling Icewind Stalwart until Glorious Protector enters the battlefield.
4. Resolve the Icewind Stalwart trigger, blinking Glorious Protector.
5. Repeat from step 2.

This clever loop begins with Teleportation Circle quietly kicking things off at your end step to blink Glorious Protector. As Glorious Protector reenters, it triggers to exile Icewind Stalwart, which in turn triggers its own entry ability to immediately blink Glorious Protector right back out. Because Glorious Protector is leaving the battlefield, it releases Icewind Stalwart from exile, setting up the entire cycle to repeat endlessly. This self-sustaining engine generates infinite enters-the-battlefield and leaves-the-battlefield triggers for your entire team.
