There are two things that could happen because of this
Rush characters and damage based removal
Retrigger Sephiroth's transform ability over and over to build up those emblems, before building up a board and sacrificing them all in one big burst of damage
Of the two new Rise of the Floodborn Starter decks, Might and Magic is stronger in my experience, but it is also slightly more complicated to pilot
It also cares about death triggers of Clerics, although it adds an element of white by reanimating them as well
This March, the next set of cards from Disney Lorcana will hit shelves at card shops and other retailers, and in previous announcements, Ravensburger detailed the starter decks and other products launching with Archazia's Island
