Looking for a second champ

Hello. I have tried Viego a few months ago and I feel in love with the champion, been pretty much OTPing him for 5 months now. My question is, what would you guys suggest when he is banned or picked. I've been thinking a lot about Bel'Veth, with the reset on R and all that, they seem somewhat similar, or Diana, as she is quite simple. Do you guys have any other suggestions?
