How it works

1. Activate a mana-producing creature by tapping it, adding at least 1.
2. Activate The Jolly Balloon Man by paying 1 and tapping it, targeting the mana-producing creature.
3. Ertha Jo triggers, copying The Jolly Balloon Man's ability, targeting Little Bear.
4. Resolve the copy of The Jolly Balloon Man's ability, creating a token copy of Little Bear that is a 1/1 Balloon with haste.
5. When Little Bear enters the battlefield, it triggers, untapping The Jolly Balloon Man.
6. Resolve the Jolly Ballon Man ability from step 2, creating a token copy of the mana-producing creature that is a 1/1 Balloon with haste.
7. Activate the mana-producing creature token by tapping it, adding at least 1.
8. Repeat from step 2.
