you can certainly get tarannis and the new mystical packs with this file. Actually I got everything on game version 18.104.22.168. You just have to patch the file so you can keep the items you get and go to Inventory: GetItem and left click on sigle item and you will see the hash ID with a last digit with many zeros and right-click on it. Then, you will see a table with delete this record and change record, go to CHANGE RECORD and next VALUE. Finally change that code from one of your choice from the items dump listings of codes and you can get anything you want in-game by pressing toggle to get item and tha's it. That's the way it worked for me I hope it works for you as well. Have fun!
