Well this is my first guide its not too detail sorry for that its work for me about 5 games so far in with a great team comp and juggler which allowed me to snowball each game so far a 5/5 wins with my friends because they know what I am doing and how to compensate to help out the top lane not saying that this isn't a hard build though this guide is more based around if your facing a another fighter/ close range champ OH AND BY THE WAY READ THE NOTES ON THE ITEMS

The runes I picked are for maximizing his w damage in a early game and giving him some poking power for his q

Cons:OK pantheon we all know his cons jump him after his w or his q-w-aa-e-q combo or the 1-2-3 punch another thing is he has no real escape mechanic. and he falls off late game, and his ult is easily escaped so work with team mates to either cutting some one off or plow into a team fight your ap/ad hybrid should give your way more damage even on the outer ring
oh another con is that counters like mundo/tank counter pantheon hard after lvl 6

Pros/ his q throw your manliness out there poke poke poke with his big rod
another pro is if your chasing some one down leave a minion behind and save your w if you know you can't get the kill when running back w on a minion.
