Big Blue!!
This stage is fair, fun, deep, and intense. The track adds one heck of a level of depth, the stage doesn't give any significant advantages, and the movement keeps things fresh every time with the slight randomization but doesn't give games away to luck. It forces the player to adapt and use it to his or her advantage, but unfortunately, it was wrongfully banned under the "infraction" of "distracting from gameplay" (Pretty much just like the heresy laws). This stage was banned by johning yet the people who ban it say "no johns". This stage drove me to start the banned stages tournaments (the links to the rulesets are in my signiature, click on the acronym of the game it's for if you want to view them, also, please post suggestions if you do view).
