#Going to post this here since unfortunately the other post was deleted before I could respond to your comment.
Your response to me claiming that Enchanters are Pyke's hardest matchups: "Or maybe the fact that more people agree with me than you shows that you are wrong by miles? But you know."
1 - I've got 500k mastery points on Pyke.
Does that mean I know everything and I'm the best player in the game? No.
But that does mean I've got a lot of experience and from my 700+ games: Enchanters are always the best pick into Pyke for the reasons listed above. By the way, you haven't given a single reason as to why you think they aren't a good pick into him, you've just said that I'm wrong (which is incorrect.)
2 - Hey, maybe my experience doesn't matter at all. So let's ask other people.
##Counterstats.net lists Rakan, Janna, Zilean, Sona, Soraka, and Nami as some of Pyke's hardest counters.
##Rankedboost lists Nami, Sona, Janna, Soraka, and Lulu as some of his hardest counters.
##Champion.GG lists Sona, Nami, Zilean, Janna, and Lulu as his worst matchups.
The only tanks on any of these lists are Leona and Nautilus, who aren't consistently good and usually only win in the late game.
3 - 3 websites still not enough information for you?
Let's check out MOBAfire, where some of the best Pykes from across the world come to share their information.
Here's Bizzleberry's guide on Pyke - Bizzleberry is a Diamond 1 player on EUW, his guide is also the most viewed one by far. Pyke's hardest matchups according to Bizzleberry are Enchanters like Sona/Soraka/Nami and in most of his videos he goes in detail as to why he thinks that.
Here's Thefwnk's guide for Pyke - Thefwnk lists Sona, Soraka, Lulu, Rakan, and Yuumi as some of his hardest counters.
The only person who thinks that Pyke's hardest counters are tanks is Hanjaro - a Master tier player. However at that level of play, people know how to stretch out games and shut Pyke down with any champion. He also lists most of the tank matchups as "skill matchups" and some of his information doesn't align with other guides of the same level.
Also, pretty much everyone in the Pykemains Discord agrees that Yuumi/Sona/Soraka/Nami are strong into Pyke.
#So, let's recap.
I've got 500,000 points and 700+ games of experience on Pyke. I've provided 3 separate websites that go in detail as to what counters Pyke with the highest results being Enchanters, not Tanks. I've also got multiple guides from players ranked anywhere from Gold-Diamond+ that list Enchanters as his hardest matchups. I also spend a lot of time in the Pykemains Discord, where we constantly debate about Pyke's performance and counters, the general consensus of which is that Enchanters tend to be his hardest matchups as they have the tools to beat him.
You've got anywhere from 1-4 votes on a Boards post, a website known for it's nonconstructive discussion where people with actual objective, statistical evidence get downvoted and bashed because they don't agree with the majority of people here, which by the way, is NOT representative of the playerbase at large, not by a long shot.
