The Bakugan Wiki Twitter page has recently shared an image of the unreleased Shields of Vestroia Card Collection pack.

Usually there are 3 packs per set wave. So there were 3 for Armored Elite, 3 for Fusion Force, and supposedly 3 for Shields of Vestroia. Unfortunately due to the pandemic, the Shields of Vestroia packs were not released. There was 1 that was previously shared by a youtuber for the Dragonoid x Tretorous pack (which I am unable to find at the moment). This is the 2nd pack from Shields of Vestroia which show the "Cloptor x Apollyon" DEKA card (see picture)

Unfortunately this item is listed on doordash, so 1) the seller is not shown, 2) there is no way to message the seller. Only if you enter a postal address that is near enough to the seller that you have the option to buy this.

Just have to wait to see if anyone manages to buy this.
