Ashur Tablets for zero

Howdy.

Maybe my search-fu is currently weak, but I couldn't find comments on this.

The original question from a RL game was:
Am I allowed to choose zero on a completed set of Ashur Tablets thus taking no card in my hand?
Yeah, obviously that doesn't make a big difference, because you can choose one and discard that one card again.

This leads to the derivative question:
Am I allowed to complete a set of Ashur Tablets while my ash heap is empty?
Thus choosing zero, gaining three pool and moving no card to my hand.

Might even happen with a Trochomancy predator

I don't see why not - up to 13 includes zero.

Yes, you can play a third Ashur's Tablets when you have no card in your ash heap.
