Hey Guys,
thats my way of playing Pantheon, i like it cuz i think Panth is a great champ who can deal great dmg without beeing killed. He's a strong farmer and his passive gives him a big atvantage vs. other AD solo topper like GP. Especailly in the early game his e does insane dmg and u can do easily first blood with a fast gank!
Here are some alternative items:
Instead of Mercury Treads u can use Berserker Graves if u dont need the Tenancy of it
U can use gp5 items e.g. Heart of Gold, Philosophers Stone or Avarice Blade
if need need the passive or the health/mana of Banshees Vail u could buy it instead of Force of the Nature.
And if u think ur still not tanky enough, dont buy Phantom Dancer, buy Guardian Angel. Its also a great item for Panth.

some Pros/Cons:
+ great early game dmg
+ his lane is good gankable if u use ur W right
+ Panth doesnt need Teleport! He got his ult... ;)
+ his passive is great to dominate the toplane

- in early game some mana problems


Laning/Farming:
It's not very hard to dominate the toplane.
Just stay behind ur Creeps, lasthit as much as possible (use q for minions that are far away/if ure pushed back) and harrass ur enemy..
The easyestway to harrass him is to spell ur Q.. but that costs much mana and isnt very effective, so jump ur enemy with ur W give him 1 hit, spell ur E, give him the next Hit and go back behind ur creeps.. u should get less or no dmg because of ur passive.
If u got already a B.F. Sword when u was first time base u should just pwn ALL ur enemys, so dont forget to gank (u dont have to hit with ur ult, it can be a good teleport too ;D)

and never ever forget to buy wards, Wards, WARDS!!!!


Now ur ready to join the fields of justice.
