Do certain avatar campaigns come back?

Hey everybody just wondering if the avatar campaigns cycle through. What im asking is that i missed the demon avatar chest in july and because it said limited time i thought,thats it no more demon chest. But ive read the demon chest released in february and april. Is there like a cycle to these avatar campaign chests?Or is that the devs just chose to release these randomly?

 

It's called the waiting game. ^_^

 

I don't know about a cycle, but ava chests usually return every once in a while, so you might see it back soon. Try checking the shop everyday because some ava chests only return one day at a time.

 

I've seen every set come back except for gambler
