Crossbreed Labs

The Unstable Crossbreed Labs ({G}{W}) is a Bablovian geniocracy, ruled by geniuses, made up of creature hybrids who have used their inventions to create a perfect society where everyone is their true self.[1][2] The current head of the Crossbreed Labs is Dr. Julius Jumblemorph.[3]


The Crossbreed Labs Contraptions do one of three things:

  1. They enhance creatures in different ways, always making them bigger.
  2. They help you get or cast more creatures.
  3. They have effects based on the power of target creature you control.

These effects tend to play into the creature-building flavor of the faction.[4]
