How it works
Activate The Jolly Balloon Man by paying 1 and tapping it, creating a token copy of Village Bell-Ringer that is a 1/1 Balloon with flying and haste in addition to its other types.
When the Village Bell-Ringer token enters the battlefield, it triggers, untapping all creatures you control.
Activate Thermopod by sacrificing Village Bell-Ringer, adding at least one mana.
