The Jolly Balloon Man + Ertha Jo, Frontier Mentor + Breaching Hippocamp

The Jolly Balloon Man

Ertha Jo, Frontier Mentor

Breaching Hippocamp

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 Breaching Hippocamp.
4. Resolve the copy of The Jolly Balloon Man's ability, creating a token copy of Breaching Hippocamp that is a 1/1 Balloon with haste.
5. When Breaching Hippocamp 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.

This wondrous transmutation begins when you set Ertha Jo, Frontier Mentor upon the battlefield, turning her keen eye toward every ability you set in motion. With her watchful presence, you activate The Jolly Balloon Man to forge a fragile, fleeting copy of Breaching Hippocamp, whose arrival immediately untaps The Jolly Balloon Man so the cycle can begin anew. As Ertha Jo doubles your activation, you simultaneously conjure a frantic copy of the mana-producing creature that funds the whole marvelous engine.
