This series is to introduce and experiment with the idea of "scrap", which is a pseudo-resource for gravity that gets created as a result of cards being destroyed.
The idea is that the gravity element allows the elemental to collect the leftovers pieces of destroyed permanents and armor / fragments of fallen allies.
These scrap pieces are collected into "scrap-piles" that can be used to fuel various cards or can be redeemed for quanta.
What are scrap piles?
-------Cards in series so far---------
Note: The art for the last one is a stereogram, so you can get a true 3D illusion by crossing your eyes till the images overlap
... if people like this, I will start doing more of them.
