Wow.. that could get all kinds of fugly if combined with mass CC like dessication.
The potential for mass devastation is pretty perfectly offset by the potential to backfire if one of your own creatures dies, so it works beautifully.
Death effect trigger makes me wish it had some kind of tie in with the

element (maybe make a hybrid? it actually has a finished card back art concept:
Russianspy's Card Back Art idea), but otherwise I love the card idea.
