I've been thinking a lot lately about how certain themes are rather underdeveloped and therefor in need of some love.

After having had a look at Barbed Necrath and Hypnotic Banshee - two cards rarely seen in constucted but often seen in sealed - there is a ample room to extend a theme centered around their abilities.

However, I would probably give new abilities to Necrath and Banshee (based on moves) and create new cards for Elementals based on their abilities. This would (a) fit into Abrixian Sparker theme and (b) perhaps help Elementals to become a viable, standalone deck option.

One could do this simply by making cheaper/more expensive creatues with more or less the same abilities and Necrath and Banshee.

An idea in its crudest form, but still an idea
