Hello, and welcome This is my pantheon build, from what i seen havent seen 1 like it. So use this and read my guide,. Also, He doesnt have much survivalbility. But he can ussally 3v1 in 5v5.

Pantheons build focuses on Critical, damage, And attack speed. For the runes as you can see will help you greatly.

Exhaust is a great aspect in LoL for you can slow if needed to get away or to catch them. Ignite is used for cheap and easy kills to get gold for your build faster,.

Pros

Pantheons stun + Heartseeker strike. Takes them down fast.

Spear shot if there running away and are about to die

Can stop Nunu's ultimate as in Katarina's or any other ultimate being able to be stopped

Cons

May die if stunned in teamfight if you are being focused.

Stun the opponent player if they are chasing your teamate if he/she is about to die, giving you and your team mates time to take him down.

Thanks for looking at my build, i am new to posting builds as you can tell. Have fun and win good.
