Sandbox Magician

Strip it off
And scale the wall
I am the mask
That talks inside the concrete flesh
I am the king
Now tell me nothing
I am the fool for a day
Concrete playground
Hides the valley
Make me the king
So I can strip it off
Who is the fool today?
Friend?
A new idea
From your stagnant mind
And you must always
Fall before the clown
I can beat you
I can cheat you
Can
I
Be you?
