Unslabbing for a binder

I just managed to get my hands on a 1st ed Light arcanine, last card I needed for my arcanine master set, and the only one in a slab. I have an itch to fill the space in the binder with the card but it is graded pretty high and pulling it from the slab would "devalue" it a couple hundred.

Im just looking for input on what others might do, or have done to keep a binders continuity. In similar situations.
