Agrus Kos, Eternal Soldier + The Jolly Balloon Man + Orthion, Hero of Lavabrink + Ashnod's Altar

Agrus Kos, Eternal Soldier

The Jolly Balloon Man

Orthion, Hero of Lavabrink

Ashnod's Altar

How it works

1. Activate The Jolly Balloon Man by paying 1 and tapping it, targeting Agrus Kos.
2. Agrus Kos triggers, causing you to pay 1R/W to copy the Jolly Balloon Man ability targeting each other creature the ability can target.
3. Resolve all Jolly Balloon Man abilities, creating a token copy of each other creature you control that is a 1/1 Balloon with haste. As needed, put the oldest Agrus Kos and Orthion into your graveyard due to the legend rule.
4. Activate two creatures by tapping them, adding at least R/W.
5. Activate Ashnod's Altar twice by sacrificing two tokens except the Orthion or Agrus Kos tokens, adding CCCC.
6. Activate the Orthion token's first ability by paying 1 and tapping it, targeting the Agrus Kos token.
7. Agrus Kos triggers, causing you to pay 1R/W to copy the Orthion ability targeting each other creature the ability can target.
8. Resolve all Orthion abilities, creating a token copy of each other creature you control with haste. As needed, put the oldest Agrus Kos and Jolly Balloon Man into your graveyard due to the legend rule.
9. Activate two creatures by tapping them, adding at least R/W.
10. Repeat.
