I did something like this in the arena one time. It didn't do that well, but that was back when the nymph was still a 1 attack creature, and it won by deckout. People seemed to really like it, though, and if memory serves it got a lot of thumbs ups for uniqueness. I definitely think it has potential, and I'd been thinking of trying something similar. I'd use way more nymph's tears and take out holy lights myself, though. Morning Glory should also do pretty good here for another source of damage that's indestructible as well.
