The kind of gyms that appears when you need coins

I faced 4 gyms and every one of them had this pattern of blissey>chealse>snorlax>metagross>muk

Or something near it.

Speacial shout out to ceroldanoite0 e cerolfininho0, probably 2 accounts of the same guy that was spamming blisseys and chealses around the City.
