I recommend trying out KAY/O. He was a lot easier for most other initiators for me to pick up, and he's amazing at setting up your team. You have a lot of consistent, guaranteed value with him regardless of how you perform, simply because of how his kit works. And the way he's played feels to me similar to Fade's in how aggressive you should and shouldn't be and what fights you can take.

He's also in a really good spot in the meta right now. He's always been amazing on Ascent and Breeze, but I'm seeing quite a few pro teams use him on several map's, so he's seeing decent play on pretty much every single map in rotation with the exception of Split and maybe Lotus (though we could be losing at least one of those maps within the next month).

I do suggest you keep your options open, though. Fade is still a great pick on both maps KAY/O isn't seeing much play in, so definitely keep her in your agent pool. Learning Cypher also isn't a bad idea, especially if you need to fill sentinel. Diversifying your agent pool and having a few picks for each map instead of just one isn't a bad idea, the way I see it. That's coming from a low elo flex player, though, so feel free to take that with a grain of salt.
