I agree with Getawu. Here's the reasons why I don't play with Anubis. Anubis has priority target over all your other creatures so he'll get congeal'd, gravity pull'd, lanced, etc. as soon as you play him. If you're playing with Hourglasses in your deck, it's tough to play Anubis earlier. He's usually played later in the game when you already have things under control. If you don't have Hourglasses (like in a 40 or smaller deck), you usually don't have the space for him in your deck since having extra copies of other key cards is more important.
Having said that, he is really great against some of the harder gods like Seism, Rainbow, and Scorpio. He just has to survive that first wave of creature control.
