Jerboa III's Curse

Creatures can't be regenerated.
Jerboa III's Curse enters the battlefield with 15
oil counters. Whenever a player casts a
noncreature spell, remove an oil counter.
If Jerboa III's Curse has no oil counters, it gains "Players can't cast noncreature spells"
"I hereby enchant this candleholder. When I shatter it,
I shatter the power of all current animus dragons."
