When Burdened Aerialist enters, create a Treasure token. (It’s an artifact with “, Sacrifice this artifact: Add one mana of any color.”)
Whenever you sacrifice a token, Burdened Aerialist gains flying until end of turn.
Burdened Aerialist's ability will trigger whenever you sacrifice a token for any reason, not just when you sacrifice Treasure tokens.
