Commander Liara Portyr + Restoration Angel + Aang, the Last Airbender

Commander Liara Portyr

Restoration Angel

Aang, the Last Airbender

How it works

1. Declare two creatures as attackers, ensuring to attack two different opponents. Commander Liara Portyr triggers, causing spells you cast from exile this turn to cost 2 less to cast.
2. Cast Aang by paying its mana cost.
3. When Aang enters, it triggers, exiling Restoration Angel with the ability to cast it from exile later.
4. Cast Restoration Angel from exile by paying 0 due to Commander Liara Portyr.
5. When Restoration Angel enters, it triggers, blinking Aang
6. Repeat from step 3.
