I said "could" not "is". I do not posses any decent tools to test my claims and this isn't a card that can be balanced with intuition. I'm trying to point out that this once should be looked into with extra caution.
No ideas for a deck though.
O, ok, Accepted. Zanz does a good beta and the community is pretty good at cracking cards straight up.
I measure cards with maths and then some runnings against decks. I misunderstood an thought you already found a loophole.
Something bothers me.. Why is there 
in that card?
Look at creatures, then look at that card. Is that really a place where a Rustler would hang out?
LIfe isn't Good or Evil, like all elements it just exists or doesn't.
Where in the world of elements would a place exist where Darkness and Life energy overlap? Here.
Though a Rustler might not hang here, requireing Light for its ability, a Toad would.
If there was a Life creature that needed Dark it would hang here. A Lichen that ambushes from the limbs, A treefolk that would rather hide in the peaceful quiet dark than be exposed to other creatures actions. I'm sure the elements world is not finite to what we currently have.
I like the art though. Looks just like hand-drawn. Very nice.
That Vector tool gives some nice results if you are prepared to fiddle.
