It isn't a living being. It was created by a god and its sole purpose is to purge the impure!
As for the protection from you, It is assumed that your player is the god that brought it into being. (Or at least that is what is brought to believe!) Personally, I would make thy own creations impervious to thy rage. But it's far from invincible from your wrath!
Edit: Forgot to mention that it's your flame inside of it! :) ---> That is why the flavor text changes perspective from first and third person oddly!
I SUPER like this design. excellent work. only thing i'd have done different is I would have went blue/green for simic and made it look like a cloning facility or similar to pics like miming slime and phantasmal image. I'd use simic because they use slime alot which is easily moldable and they have no quarrels killing things to make their things better. Least that's the base thing i would do. perhaps look into making the survivor more rewarding to encourage people to pick move valuable permanents. id say give clone 2 +1/+1's but that only works for creatures not other permanents but something along those lines. otherwise casting it could just mean everyone picks 2 of the same basic land. however for such low mana cost that isnt necessarily a bad thing and i wouldnt say its imbalanced just something to consider. :)
sorry for the wall of text your card just really got me thinking lol
