New items for Black Market Brawlers?

I was kind of wondering, the first Black Market Brawlers was basically an item test for ideas within the Rito staff. I was wondering if and when the Black Market Brawlers hit rotating queue, would new items to test new ideas appear or would they just be hitting the special mode for fun. What are some items the community would be interested in seeing. Me personally, I'd like an item that allows a mine placement, like a hextech leg dismemberer that provides small vision and damage causing landmine or even damageless but slows targets and grants vision of those effected.
