Pantheon Support!
I know, I'm. Crazy right? I've mained pantheon since shortly after beginning league and I've found this excellent strategy that works for me quite often. Let me know what you guys think, and help me brainstorm on good ADC's for pantheon. I've noticed that he works best with bursty champs like Ezreal and Lucian (Pantheon and Lucian is AMAZING)
STRATEGY: The strategy behind Pantheon support is to go glass cannon early game(full AD) and Armor Penetration, and bruiser late. Even though most supports will take exhaust Pantheon should be using ignite to help give an advantage in lane, and have extra damage and healing reduction. Teleport can be used if you are focused less on your lane and more focused on snowballing top and mid. (Pantheon's ultimate with teleport can have almost constant threat across the map.) Start with your W so that you can have a stun leap, this also refreshes your block and allows you to put a full charge on your block passive, so you can have a Proc active and 3 stacks at level one. Which is going to be a lot of mitigation for damage provided you don't let the enemy support break the block. If you do it correctly you can block almost every enemy ADC auto attack in the laning phase. After W get Q and start poking down your enemy ADC. Usually I pick up first blood at level 2. I have learned that Your ADC should share the first few kills because of how snowbally Pantheon is naturally, after you pick up some gold, first back you will roam to mid and try to pick up another kill, then go back to lane until 6 and then once you hit 6 you leave the lane and use your ultimate to start snowballs in the other lanes. In essence, pantheon support is meant to quickly get bottom lane ahead because of the high kill potential, then turns the whole game to your team's favor by visiting other lanes and using your lead to snowball your team.
PS Pantheon's mana costs are very high so if you plan on keeping a lot of poke and pressure you can invest in a sheen, which you can use later to build a tanky item. Buying a sheen will roughly double your mana and allow for an annoying amount of poke.
