How many champions should I know well before starting to play ranked? I am right now level 27 and 28, and it starts to get close...

atm I can play Swain, Leona, Riven, Ashe, Udyr, Karthus, Caitlyn but I still have to buy Swain, Leona, Caitlyn and Udyr (I got Udyr on my level 28, but the others on my level 27, so I'm going to play that one ranked). There are also a bunch of other champions that I sometimes play with (Lux, Morgana, Heimerdinger), but I don't think I like then enough to buy them on my second account too.
