Welcome!
Cube development:
The origins of this cube was that it was a Card Kingdom cube, so its began as a budget/intro cube.
This was then upgraded for about $50 by Cube for Two - a YouTube channel who also have cubes on Cube Cobra. They then given this cube away as a prize which I was fortunate enough to win!
I then made some slight changes; partly as I wanted to add some pet cards, and also newer cards that came out with new sets.
