How it works

1. Activate up to seven mana-producing lands by tapping them, adding at least 5.
2. Activate Livio's first ability twice by paying 2, exiling Great Whale and Village Bell-Ringer with aegis counters on them.
3. Activate Livio's second ability by paying 2 and tapping it, returning Great Whale and Village Bell-Ringer from exile to the battlefield.
4. Village Bell-Ringer and Great Whale enter the battlefield, triggering their abilities.
5. Resolve the Great Whale trigger, untapping up to seven lands you control.
6. Resolve the Village Bell-Ringer trigger, untapping all creatures you control.
7. Repeat.
