Machine said: As an aside: do the gems fill the card on the bottom of the pile? or the most recent card with buried that enteren the GY? Yes, that's how it is explained in the tutorial. You can also check the exact wording of this ability by tapping on the highlighted text on the card. There you will see the same explanation.
I found today that graveyard gems are created up to a max total (so if there are 3 already, uto makes only one)
Is that the way it is supposed to be?
