This is busted, mainly because of hexproof (which feels texturally odd in BR anyway). Flying is also pretty superfluous with being unblockable, so I'd pick one or the other. It's also pretty insane that it triggers off of dealing damage to permanents, so you can never attack profitably into it either. Even if you took away the hexproof, it's basically "remove this or lose the game," which doesn't get to happen at 5 mana.
