Why would he need an Anubis?
Worst case scenario, the weapon gets destroyed by the other player instead of being destroyed when you play something over it. It's not like you animate a weapon as soon as you play it unless you expect it to last longer that way.
Just a thought, Eternity is really, really good as anti-creature control; you can heal your creatures of damage and status and remove any buffs theirs get. They have to kill them in one hit to get around it, and they can't rely on Heavy Armor to do it.
Why the Deja Vu though? I'd think you'd be very short on time quanta as is and it doesn't really add anything to your deck. Unstoppable might be a good card to consider adding because it lets your Oty pierce shields and eat 5 HP dragons right away.
