due to the recent sona rework on PBE she seems more like a mid, and is really powerful so ur gonna want to go sona mid for that damage and cunfusion for the enemy team (late game you will also provide lich bane effect to team, insane heals, and high move speed buff)bot lane is the shiel wombo combo bros. their job is to carry the team on their proud manly backs. top, you can do whatever the hell you want honestly, i recommend either a Alistar, Ezreal, or Vayne but idc. next for jungle you are going to go Maokai in order to give your team bonus armor in teamfights and provide mad ganks, cc, and joints

bot lane is going to be special, you will be happiest against enemies with lots of skill shots specifically one that doesn't need a map. with you duel shields your job is to make them sad and harass them, not letting them get much farm until you both reach level three, then you engage on them getting first blood and a double kill, after this you basically just slaughter them whenever they walk into lane and take dragon whenever it is up with you jungler while pushing lane to their inhibitor (at least until midgame when you are needed for teamfights)

now you have reached midgame, at this point you wait for a good chance and engage with a tree to the middle of their team who proceeds to ult and pass a joint to braum, braum ults knocking the entire enemy team up and he passes the joint to Yasuo, Yasuo ults the entire enemy team and proceeds to do damage and he passes the joint to Sona who immediately follows up with her own ult stun locking the enemy team while the rest of her allies eat them alive she then passes the joint to her pet cow, Alistar promptly knocks up the enemy team and ults so that he effectively takes no damage thanks to maokai and his own ult.

Cons
-No ranged adc
-Your mid lane is squishy and will have to be careful
-your top may or may not have a tough time based on who he is against
Pros
-Your bot lane is invincible
-Your mid can heal herself and after getting mana regen should be fine
-Some ganks from Maokai for your Top Alistar should make him an un-killable beast
-you have insane cc and a great wombo of death

have fun breaking the meta, winning games and feeling like a horrible person while listening to smoke weed everyday
