Everyone's Profit

Draw a card, then either gain or lose 1 life.
Then, each opponent may do the same. If any
one of them does, you may repeat this process.
Then, for each card drawn by other players this
turn, create a token artifact named Treasure with
"{t}, sacrifice this artifact: add one mana of any
color".
"... but especially mine."
- Lummo, of the Shivering Siren
