This card has real potential. At 3 mana, it is extremely affordable for a 5/4. His ability is one of the easiest to build around and it begs you to do so. While other gods just give you value based on doing what you'd do already like draw a card or attack with creatures, this will benefit from being built around.

Want to play a bunch of wrath effects and be the only one who benefits? Get there. Want to next level Immortal Servitude? This can enable that. This is a bizarre form of reverse reanimator. You only benefit from cards you already had in play and this won't help you get them there, but it will keep them there. If there were any sort of Blood Artist effect, this would be even better, and maybe this can be tested in Modern. I can't think of any other card that does anything like this, and unique effects maintain their price better than "me, too" cards. I haven't seen price data yet, but I imagine he will be hyped early. This is quite good, though whether it maintains value depends on whether his effect is too far ahead of its time.
