MTX suggestion for Bone Storm and Bone Cage

Bone Storm: Swords made of metal materialize instead of bone shards. With the materialization animation being shards of metal forming the swords. When empowered by power charges, the swords have glowing runes, colored the same as a power charge. Pins with this MTX on show the monster being pinned by several swords pointing downwards stabbing into the ground.

Bone Cage: Spears made of metal jut out of the ground, the lingering bone cage is also spears, just less of the shafts sticking out of the ground. Pins with this MTX on show the monster being pinned by several spears coming out of the ground.

I figured it would be a nice thematic combination of MTX.

I welcome all criticisms and other ideas for how the MTX could look.
