Magic Tricks

Tornado is so great !
I was immediately sold for buying a pack of three refill packs, at a very affordable price !
And I must say I was a bit disappointed, because there are only 4 different sets !
It would be an issue for non-pro like me, performing for the same group of friends, which could guess why there are only 4 and 7 involved in that beautiful trick (trick that they will remember, and that they will absolutly demand to see again, at the next family meeting... because it's so good!)
Why didn't you design a refill pack with more options? It could be an idea, and, if you're projecting to do so, I'm in!
