## Official Rulings
- *(2019-11-12)* It’s unlikely the Swarm of Locus pun will survive creative review. They’ll assign a new creature type, as Locus can’t be both a land type and a creature type. For now, the triggered ability of Swarm of Locus counts both the temporary-creature type Locus and the land type Locus. Other effects that refer to one won’t affect the other.
