Anyone know the company that made those mats?

Which location are you talking about? Not every store gave mats to the Top 8.

The one in this video. https://m.youtube.com/watch?v=NbFcwZ6fYNg

Me thins them are custom made, but the Galel Force 9 looks quite similar, I have their Gas Cloud, Fiery and Ice Planet

That's the mat from the Monroeville, Penn., regional on May 3. The store, Mr. Nice Guy Games, had the mats custom-made.
