IMO avoid making this deck at any cost. It works basically as an OTK deck. However, BLS has 0 protection. In a format full of floodgates, canadia kiteroids etc. it hardly wins any matches. Once BLS is gone you are finished. However, the worst part is getting BLS from an old box full of bad cards... The following picture describes my feelings...
My overall views on this deck
Battle: A
(Due to the support that could double banish and banish from hand.)
Complexity: C
( It is really easy to use and you could get 1tk.)
Defense: D+ to C-
(has some defense with super soldier shield, but it wont trigger if interrupted upon summon.)
Price: Expesive
Support:B
(but needs more def support)
Overall i would say that BLS is a Rogue deck for now.
I played with it for about a month after spending about 7000gems just to get those 3 BLS. This deck relies 90% in luck and going second. If you go 1st you either have to summon a Sonic Bird set a CC or a bluff and cross your finger to survive. Next turn cross your finger once again hopping that your opponnent has no traps/hand traps and go for the big hit, which rarely happens.
