Appa, Steadfast Guardian + Hoarding Broodlord + Felidar Guardian

Appa, Steadfast Guardian

Hoarding Broodlord

Felidar Guardian

How it works

1. Cast Appa by paying 2.
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 and tapping Appa and another creature you control.
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 ingenious loop turns Appa, Steadfast Guardian into an engine of continuous reincarnation by using its own airbend ability to exile Felidar Guardian. Because Hoarding Broodlord grants convoke to spells cast from exile, you can cast Felidar Guardian for zero mana by tapping Appa and another creature to pay its cost. Every time Felidar Guardian returns to the battlefield, its entry trigger blinks Appa, resetting the loop and letting Appa's second ability generate an endless army of 1/1 Ally tokens while fueling infinite storm count and trigger effects.
