It’s got obvious reprints and a random new card. Also no hints for CROS, too bad.
The contents are:
Valhalla, Hall of the Fallen
Scrambled Egg *NEW!
Melchid the Four-Faced Beast
(1) If a monster you control is destroyed by battle or effect and sent to the Graveyard: Special Summon 1 “Sonic Chick” from your hand, Deck, or Graveyard.
