Ok, lets figure out whats in this puppy!
it looks like it will have 87 Normal Advent Cards, lets break the known cards down:
Ryuki - 12
Knight - 9
Sicssors - 4
Zolda - 7 (provided they include the never seen second Guard vent that uses Magnugiga's kneepads)
Ouja - 6 (Venosnaker's cards plus Unite vent, Genocider and the Doomsday Final Vent)
Raia - 4
Gai - 4
Tiger - 5
Imperer - 3
Femme - 4
Verde - 4
Ryuga - 5
Odin - 5
Aleternitave - 5
Survive Cards - 3
Etc - 5 (Steal, Return, Blank Sword, Seal, Contract)
Thats 86 there, so one is a mystery.
Plus we will be getting (i think) 39 Foil Versions as well, most likely being all the Advent and Final Vents and some others (Time Vent, Strike Vent, Genocider etc).
Then the Three Survive cards that look to have a speical foil treatment.
