Devious Freddy

At the beginning of your upkeep, roll a six-sided die. If you do, you may pay X, where
X is the result. If you pay, create a 1/1 red
Goblin creature token with "When this creature dies, it deals 1 damage to any target."
"Freddy owes me 50 schoombles after he stole my best friend's dog."
