Six sam is expensive to build?? You just need to get 2x Grandmaster, 2x Hand, and 3x Kizaru in one box (crusader I think), then just collect as many Kizan as you can on this box, together with 2-3x Kageki, and at least one Shi En synchro.
11-12 core/supp monsters in just two boxes, and yet there's armades control and brotherhood where you need to open 1000 boxes to make it usable. What's expensive again?
