I really like this idea for a Fire permanent. How about making only weapons so you could build a deck with a Flying Weapon strategy?
I think the ability cost is too much though. I like the idea of using Relics but it isn't worth putting them in a deck just for a random Weapon or Shield. Since the effect is random, just a quanta cost should be fine.
*Edit* I think it should put the card into play
In your hand makes it too expensive.
