Third champion main suggestions

I've been thinking for the past couple days what my thrid main for top should be since I will be buying skins for probably only my mains,my first pick is tryndamere which I am not getting a skin for until a new one or rework comes out but for now ill get the demonblade. My second pick is pantheon which I will be getting the dragon slayer skin.The champs I like to play are the ones that are most call "braindead".champs that I've tried but did not like were Dr.mondo ,Jax ,cho gath ,renekton ,and yorick .Leave suggestions for champs or skins.
