Glorious Protector + Felidar Guardian + Ghostly Flicker

Glorious Protector

Felidar Guardian

Ghostly Flicker

How it works

1. Cast Ghostly Flicker by paying 2, blinking Glorious Protector and Felidar Guardian.
2. When Glorious Protector and Felidar Guardian enter the battlefield, their abilities trigger.
3. Resolve the Glorious Protector trigger, exiling Felidar Guardian and any number of other non-Angel creatures you control until Glorious Protector leaves the battlefield.
4. Resolve the Felidar Guardian trigger, blinking Glorious Protector.
5. Glorious Protector leaves and re-enters the battlefield, returning Felidar Guardian to the battlefield from exile.
6. Repeat from step 2.

This elegant loop relies on the constant re-triggering of enter-the-battlefield abilities through a self-sustaining cycle of exiles and returns. By casting Ghostly Flicker, you kick off the chain reaction by blinking both Glorious Protector and Felidar Guardian. As they re-enter, Glorious Protector's trigger safely tucks away Felidar Guardian (along with any other non-Angel creatures you wish to bring along for the ride), while Felidar Guardian's own arrival trigger targets Glorious Protector to blink it right back out. This forces Glorious Protector to leave the battlefield and immediately return, which frees Felidar Guardian from exile and restarts the entire process to generate infinite entry, leave-the-battlefield, and blinking triggers.
