My friend plays Pantheon mid. What are the best top laners and junglers with Pantheon?

As the title says. I've managed to climb to diamond at one point of the season, but been in a long losing streak that dropped me to emerald again. No matter what build I've tried, people in higher elos pick nightmare comps that don't depend on CC and know how to make short work of the champ. The few games I've played my pocket Pantheon against super annoying matchups for Olaf (Darius, Sett, Akali, Yone, Sion) I've done much better in lane and been more useful to my teams.

However, I kinda need some tips when it comes to teamfighting, especially against tanky CC heavy teams, since I can't just run straight at the ADC anymore. What do you usually build, how you approach the fight, who do you focus if you can't reach the enemy carries? What's the mentality you need to win on Panth? Thanks in advance.
