AI and some mechanics, keyword sometimes bug and a card?

Hi, so using the Snapshot version for Android I have noticed that:
Vanquisher's Banner and Morophon, the Boundless when the AI chooses what type 9/10 times will choose among Humans, Sliver or Warrior (mostly Sliver) even if there is 0 cards in the decks of that creature type.
Also noticed that sometimes the Myriad doesn't work properly: the tokens don't enter the battlefield attaking but with summoning sickness and doesn't exile them at the end of combat.
Different subjects: does anyone know when the card Nacatl War-Pride will be added?
