I've seen him played both ways. From what I've seen AP is more viable. But I'm still not sure how to build him. Is it better to hybrid, or just focus on one? Any information is welcome. Thanks.

Purely just AP.
with the exception of you prob want lichbane on him.
i think because of the dfg nerf that you also no longer get dfg on him
but it may still work i have no clue

I go ap/hybrid usually nashors tooth first then ryalis lichbane and madreds

I was eventually going to try all 3 builds, but I was leaning more towards AP. Maybe I'll just skip AD altogether then. Thanks guys.
