It works. Can't build it early, but you reach a point where more tankability stops mattering, but whether fights last long enough to stack should be considered. it IS one of the strongest items in the game once stacked, but one of the weakest til then, so it's actually best on tanky fighters with on-hits, and/or inherently high attack speed. unfortunately shen doesn't have high attack speed, and the on-hit depends on your cooldowns.

It's usually too expensive to consider early until conditions have been met, but is effectively like an infinity edge for on-hit attackers. You only get it once you have crit - or here, once you have the speed or on-hits.
