The effect of the "Majesties" activate when they are Summoned. They are very strong and their effects are powerful.
"Melodies" use Music Counters to make field advantage. The music "Melodies" sound great for you, but will be cacophony for your opponent! Fermata - The Grand Finale's effect will defeat your opponent's monsters with grace.
The new "Torment" are Union Monsters that have a new feature: They attach to your opponent's monsters! They do various bad effects for your opponent's, and they you can summon the all powerful Torment Dragon, the most dangerous Torment of the bunch!
Cover Card is "Majesty of Chaos".
This booster pack is very OP and unrealistic and would never be printed but if you want to make unfair cards be my guest.
