What counter Vi ? Q & A
Counters to Vi: Essentially durable, high-armor champions who like to trade with their lane mates. Champs like Yorick, Jax, Riven, Irelia, and even Garen will do very well against Vi. Also Champs that out-burst Vi like Darius and Pantheon will do fairly well against Piltover's newest champion.
Champions Vi counters: Basically any champion who cannot withstand high burst damage will struggle against Vi. Vi does well against champions like Olaf (uses his HP to trade) and Cho' Gath (Can't fight if CC is dodged or ignored). Vi also does well against the often-banned tanks Malphite and Shen, both champions can withstand Vi's burst but cannot return enough damage back to pose any threat to the Piltover Punisher.
I hope I was able to help :)
* Also sadly Mr. Cuddowls is a little misguided as Teemo does very well agains Vi with his infamous blind + shroom + AA combo. If u want to counter Teemo personally I suggest Yorick or Gangplank.
Vi is Strong Against:
Sad that people dont understand game mechanics to the point where they dont get how a champion can counter another champion even when it seems unlikely
I will say this again, Vi does counter Teemo, Dont trust those downvotes
