This set introduces a new mechanic, Terastal Type ex card evolutions
While this playstyle can be a bit more difficult to learn than those of the other Structure Decks, the Synchro Unity Structure Deck is built with new and old players in mind and makes it easy to get monsters out on the field, making it one of the best choices for any player
Whether that is the case here remains to be seen
We could also see the introduction of Sync Stones and various other Masters EX original concepts as this game does feature a ton of slept-on ideas that would work perfectly with the TCG format
Some of those themes overlap heavily with the other Universes Beyond: Fallout precons, which seems very intentional
Between Charming Prince, Basilica Bell-Haunt, Oath of Kaya, Faiths Fetters, and my personal cheeky splash for Knight of Autumn, theres enough ETB life-gain to make a Yorion cast immediately lethal with Vito
