The Ultimate Rising contains many cards that can play their role in any kinds of decks, such as Sphere Kuriboh and Wonder Balloons. If you plan to do reroll, I strongly recommend you to get a copy of Sphere Kuriboh from this expansion.
The Flame of the Tyrant pack contains mostly monsters, putting more focus on some fire cards and creating more possibilities with insect monster combos.
The signature card the Tyrant Dragon, is a powerful dragon card that is good if you want to make a dragon deck, while The Golden Apples can be quite versatile that works in most decks, and also Warrior Dai Grepher for a strong level 4 normal card with high attack.
On January 1st, a banner describing "New card box, Valkyrie's Rage, has been added" had appeared In Japanese App Store. It seems that was an accident since the banner was replaced with another one mentioning "Neo-Impact", the card box that had been released recently.
