Goblin's Gift

Goblin's Gift enters the battlefield under target
player's control.
At the beginning of your upkeep, roll a d20:
1-9 | Create a food token
10-19 | Sacrifice another artifact
20 | Goblin's Gift deals 3 damage to you and each creature and planeswalker you control. Sacrifice
Goblin's Gift.
It's the thought, or lack thereof, that counts.
