First we have to do much damage, so that the spear the opponent very hurt. This enables us to keep the opponent away from the creeps and we can get the farm. After we have saved a lot of the damage of the spear, and increasingly we will from time to jump on the opponent and stun. Ignite and flash are the good, the magic always a pantheon should play. The Pantheon is ranked not played often, but you should tuen it is if you play well in a powerful weapon to cut the opponents the way. Pantheon is also to start a good fight team, because his ultimate slow the enemys and they can not run away easily.

Pros = He can simply start a Team Fight He has a good stun for First Blood.
He has little cooldown of his spear Can defend with the ultimate each tower.
If you want fast in one place.

Cons = It consumes a lot of mana at the beginning.
He has too much cooldown for his ultimate.
Can only focus on one opponent.

He is not a good Jungler.

To get the last hit you can sometimes use the spear as it is useful to kill creeps, but be careful as the spear consumes a lot of mana.

At the end Pantheon is one of the best champions in the game, just the total package and it can not understand why he played so little in Ranked.
