Cull solution that would actually make people get it.

This is a suggestion based on another item that use to be in the game: Eleisa's Miracle

http://leagueoflegends.wikia.com/wiki/Eleisa's_Miracle

While Eleisa's was overall so-so of an item for most it did have an interesting thing about it for a period of time. After leveling up 3 times while owning the item it would disappear from the item slot and become a permanent buff for the rest of the game.

So what if Cull were to have the same kind of effect after getting 100 CS? Cull 450 5 AD 3 Heath Restored on hit Unique passive: killing a minion grants 1 extra gold and grants this item a stack. At 100 stacks this item is removed from the item slot, grands 300 gold (if 300 is to much when mixed with everythign else nerf it to like 150 or 200) and it becomes a permanent buff increasing base AD by 5 and restoring 3 health on-hit.

Now it is an item that is worth considering and has no unjustified down ides in starting with especially for a late game champ.
