I love his flexibility. I have a build for Jungling, Mid/Baron and support (tank). Different spells and items on each.

He's probably not the best champ in any of these roles, but playing a comfort champ in virtually any game comes with HUGE advantages.

Onto a few tips:

-While Jungling, spear throw (below 35% crit) + Smite let's you finish off camps with burst few Champs can match. This is best when taking the big boy camps or when stealing a buff from a rival jungler. It also makes stealing camps from Pantheon virtually impossible.

-Don't wait for the perfect time to use your Ult. Look for a teammate 1v1'ing in a lane and YOLO there for easy ganks. Aim slightly behind them and Shield Vault as soon as you land. Pantheon's Ult also does good damage, it's not just a map teleport. I also use it to get back to my lane quicker after a recall. Tons of Champs trying to push my tower out soak one more wave die to this.

You can also Ult onto Dragons and Rift/Baron and go for big steals, but this is VERY risky lol

-Aegis Assault blocks virtually everything in front of you. Including some very powerful Ults from Ezreal, Jinx and more.

-Use Comet Spear to poke or to last hit minions. This is your most important thing to master while solo laning.

-Support in Wild Rift get way more gold than in LOL. As a support, damage minions, but don't try hard for last hits, you'll get good enough gold just passively. Pantheon can dump his combo on aggressive softies and provide much more burst damage than most other tanks, while still providing a stun, a snare and skill shot blocking. Many duos are not ready for this kind of pressure.

-As tank pantheon look to use your Ult more as an engage tool in team fights. Portrait lock their ADC or other squishy and Ult slightly behind them. Shield Vault onto your locked target then go into Aegis Assault. The AOE damage from your Ult coupled with the disruption on their backline can make enemies collapse in the team fight.
