Misterpixel is a Runescape player who is best known for being a regular in the F2P Clan Wars scene. Through his friends chat, He has hosted many wars at Clan Wars throughout the years which are called "playoffs" by players who attend them. Because of the number of wars he's hosted, he is one of the most well-known F2P Clan Wars players of the modern era.
The most famous war he hosted was on May 2nd of 2020 against xxDark Horse. Together, they managed to mass enough players to have a 100 vs 100 war for 5 rounds straight which is almost unheard of in the largely dead pvp community in RS3. Misterpixel's side ultimately won 3-2 despite having less players each round. Someone happened to record the entire fight and you can watch it here. https://www.youtube.com/watch?v=wlmqXozWMGI&t=9s
Misterpixel is also friends with Furious Swag and Lively Void who are the leaders of Team 0verkill and Crazed Pkers respectively. The trio have hosted playoffs in early 2020 to bring back Clan Wars to it's former glory while coronavirus keeps everyone inside.
