If you're going to stick to a one-word name for a weapon, try using "Dynamic", the energy that produces motion and change.
I want to try this out in a crusader deck Off Topic: @ Zblader and Nepycros: "Possibility"...
It's a stock image, I just think it's better suited on another card, doesn't exactly look like a weapon, I'm working on something though, should turn out nice if I dont run into any issues.
