Jace 2 3rd ability crash [Can't reproduce]

Now I'm not sure if this was because if the card effect or my phone, but when I had jaces 3rd abilitys on play and song of creation in play, I decided to use inspired Ultimateam to deal ten damage and draw 5 cards, to help buff  kenfu and dungeon gist and the thopter tokens, yet instead it crashed when it was buffing drawing and copying all at the same time.
