Nothing in the current line is completely like the Rival, but I would suggest the Omen for the mid lane read that you are looking for, Omen can handle oil and starts up pretty early.
Another ball in the current line that will give you a good midlane is the Benchmark, great predictable motion, nothing too jumpy.
I really think that you will end up liking the Omen a lot, I have a few of them and love the reaction that I get.
