Inside each starter box of Kardtects Building Cards is included an ultra rare collectible building card.  Currently the three sets available, Grisroc, Lost Desert, and Forbidden Jungle, are featuring an Ultra Rare Door card.  These building cards are great to start off collections.

Just by placing the one Ultra Rare Door card onto a card house built with the common cards found in Kardtects starter boxes makes an incredible difference to the appearance of a card house.

It adds a whole new depth to the structure.  As various other building cards are collected and added to structures, it is realized just how amazing structures can be.  Kardtects continues to add collectible cards to the Kardtects building card line up.  And to read more about Doors, read Kardtects Fun Facts on Doors.  Interesting stuff!

And here is the Lost Desert with not only the Ultra Rare door card, but additional collectible building cards:

To expand building card collections even more, Expansion Packs are available.  A builder never knows which building cards they will find in a box, but they are guaranteed to find 12 additional Common Wall Cards to expand base structures, and then 18 additional building cards of various status of common, uncommon, rare or ultra rare, featuring remarkable elements to transform starter box card houses!

Each style currently offers 50 different collectible cards and all together 150 different collectible building cards are available to enhance the wonderful fun of building a card house.
