Overgrowth Artifacts

This won't be an artifact-heavy set, but I do plan to use them to help splash reave a little bit. In a limited environment, I want to make sure somebody has enough access to reave to make it worthwhile even if they end up stuck in a different color instead of full red/black. And there's some graveyard recursion in the other three colors as well, so there's a colorless reward for recursion for those who are in neither red nor black.

The artifacts will also add to a bit of the story mystery. Deep in the bowels of Guthreham, there are artifacts of unknown provenance that seem to be in working condition. Janell has been focusing on destroying all signs of artifice in order to keep it from corrupting this world. So who is responsible for this creature here?

Janell would destroy this monstrosity. Xirn is going to investigate it. We'll see how that goes for him.
