Appa, Steadfast Guardian + Pearl Medallion + Felidar Guardian + Gathering Stone

Appa, Steadfast Guardian

Pearl Medallion

Felidar Guardian

Gathering Stone

How it works

1. Cast Appa either from your hand or from the command zone by paying plus commander tax, if applicable.
2. When Appa enters, its first ability triggers, exiling Felidar Guardian with the ability to cast it later from exile.
3. Cast Felidar Guardian from exile by paying 0.
4. Appa's second ability triggers, creating a 1/1 Ally creature token
5. When Felidar Guardian enters, it triggers, blinking Appa.
6. Repeat from step 2.

This brilliant loop relies on Appa, Steadfast Guardian to continuously airbend and exile Felidar Guardian, setting up a zero-cost casting engine where Felidar Guardian can be replayed repeatedly from exile for free thanks to the cost-reducing magic of Pearl Medallion and Gathering Stone. Every time Felidar Guardian returns to the battlefield, its enter-the-battlefield trigger blinks Appa, Steadfast Guardian right back out to restart the cycle. As this engine spins endlessly, Appa, Steadfast Guardian's second ability rewards your relentless casting from exile by generating an unbounded army of 1/1 white Ally creature tokens alongside limitless enter-the-battlefield and leave-the-battlefield triggers.
