If I'm reading it right, It's basically an SoV on a creature, Dawn.
I like it.
I wish it didn't need gravity to devour, but that wouldn't happen.
Although, compare this card to SoV, because that's what it basically is.
SoV costs... what? 2 to reduce 3 damage a turn?
This costs 7 to reduce 4?
I'd say add a bit more damage to it. 5/6.
