It can be used as a smart-trap, or a guard or something, the details are in the script.
Save the following to a txt file, import it as an ASM FFC script, assign it to a freeform combo, fill in the required arguments, and you're good to go.

;***********************************************************************
; ~ABOUT THE SCRIPT~
; This script will create a horizontal moving combo with customisable
; left and right speed and animation, that always seeks to block Link's
; path. The script does not test for collisions with solid combos,
; so the X co-ordinates of the left pixels of the Guardians first and
; last WALKABLE tiles (i.e. the ground it will walk on) must be entered
; into fields d0 and d1 respectively. Lastly, since the combo's movement
; is based on speed rather than position, faster speeds can cause the
; Guardian to "shiver" when near - but not exactly on - Link's X
; co-ordinate.
;
;***********************************************************************
; ~VARIABLES~
; (variables d0-d2 and d4-d5 must be entered manually into the FFC's
; arguments tab. For correct animation, make sure the guardian combos
; are set sequentially in the combo table as: stationary; left; right,
; and d2 is set to the combo number of the stationary-animation combo.)
;
;*d0 = x co-ord. of guardians leftmost movability
;*d1 = x co-ord. of guardians rightmost movability (- combo width)
;*d2 = combo number for stationary animation (d2 + 1 = left animation,)
; d2 + 2 = right animation)
;*d3 = determines where the combo needs to move. 0 = stationary,
; 1 = needs to move left, 2 = needs to move right
;*d4 = speed of combo moving left (requires a negative number)
;*d5 = speed of combo moving right (requires a positive number)
; [NOTE: Entering a positive number for d4 and]
; [ a negative number for d5 will result ]
; [ in the combo avoiding Link. ]

Oh wait... reading the warning... are we not allowed to post scripts? Would that be encouraging people to go unstable?
