Huh.. funny how Graviton Inferno, an older idea for a Gravity Shield, needs sacrificing too. Why is that? It's not like Gravity lends itself to it. If anything it's the opposite with its high HP creatures wanting to stay on the board. Being steadfast and having control seems to fit Gravity. Graviton Inferno required
to sacrifice, which makes sense in that it's like a forge, but in hindsight I don't think it fits Gravity to sacrifice creatures even with the help of a more volatile element. Non-pillar/pend ermanents on the other hand.. that would make perfect sense for building a wall.
But a wall wouldn't cause you to miss. It would reduce damage. Of course, Graviton Inferno already does that. It's also not very thematically sound for Gravity to.. dodge.
