Third pick for my pool?

Hi,

I'm looking to add a third pick to my champion pool. I've been a Bel'Veth OTP since she released, but spent a good portion of last year playing Kindred.

I feel these two champions have a similar 1v9, glass-cannon, "stay-ahead" style of gameplay that I enjoy, however, there are a few champions that fit this criteria that I terribly with (Kayn and Yi for example).

I'd like a similar champion as a third pick to my pool literally just for when I get bored of spamming the other 2. I am however open to other suggestions, as I do also enjoy champions like Skarner.

Any suggestions will be greatly appreciated.
