It's the right board. Entropy, Earth, Fire and Aether are in your deck, making it a quartet.
It looks decent for Elders. Since it has a lot of control, it's bound to win a lot, and it doesn't look all that slow. PU's makes it a bit less fragile as Golems otherwise would be against Elders with heavy CC, and they also add versatility. Novas will mess your hands up though, due to automulligan, and they're not very useful. I'd take them out.
