If {Zada, Hedron grinder} copies, say, {earthen arms} with the awaken cost paid, do you get to awaken as many times as it was copied?
If you cast it for Awaken then Zada is not the only target - you're also targeting a land.
Zada won't copy it.
If you copy a spell cast with Awaken while its in the stack another way, yes you will Awaken again.
Ah thank you! I always miss that wording. I hope it sticks this time
