At this point the Ashur Tablets effect is kicked off. I move 1 card
to my hand and 12 to my library. Is that the correct order? I don't
have to replace my 7th card from the rebuilt library as well, causing
me to discard a card, do I?
Name: Ashur Tablets
Master.
Put this card in play. If you have three copies in play, remove all
copies in play (even controlled by other Methuselahs) from the game to
gain 3 pool and choose up to thirteen cards from your ash heap. Move
one of those cards to your hand and shuffle the others into your
library.
You have 6 cards in hand at that time, but your hand size is still 7, not 6.
Your hand size is the number of cards you're supposed to have in hand, not
the number of cards you currently have in hand.
So you move 1 card to your hand without discarding since you're back up to
hand size with 7 cards in hand and shuffle the rest in your library, no
problem.

Correct.
