That is the part that was frustrating. Editors kept permitting this. That is not how divine gifts work. You can't "turn her into clay" because she hasn't BEEN clay for whatever untold milennia it was that she was created on Themyscira. You would need to be the Supreme divinity in order to move time backward around her until she was again a babe moments after being brought to life and THEN you could turn the baby back to clay. Unless you literally wield the ultimate power in Creation it isn't something you can do. And even with that it is a great undertaking.
