Gateway of the Six is the best thing that has happened to Six Samurai! Max out the Gates definitely!
Subtractions:-2 Sakuretsu Armor (That is a no-no!)
-1 The A. Forces
-1 Swords of the Revealing Light (This seems to be destroyed easily in today's Meta)
Additions:+2 Dimensional Prison
+1/2 Great Shogun Shien
+1 Grandmaster of the Six Samurai
+2 Gateway of the Six
I might add more changes 'lata!
The subtractions and additions don't add up.
