Poachers Knife - Gives Stacks of Teleport

How often do people actually get that item? +20 Gold and a short MS buff just don't seem to match what the other three Smites can do. I like the idea of an item devoted to Counter Jungling, but it doesn't seem to have been executed very well.

What I propose instead is for the item to be capable of using the Teleport spell, using a stack mechanic. Smiting a monster in the enemy jungle would add one stack (a monster can only give one; so no stealthily smiting and running back to it every few minutes), and after a certain amount of stacks (anywhere from 3-5; depending on how Riot would want to balance it) the item becomes usable in the same way that Teleport does.

The reason I suggest Teleport, of all spells; is that it would best promote counter jungling and jungle warding. It would be a way for a counter jungler to have an escape option if they get caught out; they could try and teleport to safety. OR, after clearing the enemy jungle they could teleport in for a gank at a far away lane. Because of that; enemy teams would have more incentive to ward their own jungle more heavily, which could cause blindspots elsewhere in the map and lead to opportunities for the counter jungler's team.

This would also give certain top laners a viable way to have smite; as they could grab Smite and still have an option to Teleport (doing so wouldn't be without its own risk, as you wouldn't have the Teleport as a band-aid option back to lane early in the game). It would cause the Scuttler to become a more contested objective; effectively giving a team more incentive to slow down the enemy Devourer jungler's stack building.
