How it works
Activate Ashnod's Altar by sacrificing Wily Goblin, adding CC.
Wily Golbin dies, triggering Nim Deathmantle, causing you to pay 4 to return Wily Goblin from your graveyard to the battlefield, and attach Nim Deathmantle to it.
Wily Goblin enters the battlefield, creating two Treasure tokens.
Activate two Treasure tokens by tapping and sacrificing those, adding two mana of any color.
