From what I can tell, it seems to be open to others. ET is having internet issues and seems to be leaving his ideas open to others to pick up. So, I think this should be fine.
The hybrid element project is pretty big too so I have a feeling they will welcome any outside help they can get.
Right now, they seem to still be in the process of getting all their card backs up and going.
Did you get this from the project page or make the background yourself? If you made it yourself, you should try submitting it to the page. Its looks good.

Gain +2|+0 and deal spell damage this turn."
or

Gain +2|+2 and deal spell damage this turn."
