Who should I vote for in the Czech Republic?!

Hi Comrades :) I have my first parliamentary election coming soon (autumn) and I'm not really sure who I should vote for... To be honest, I am sort of an anarchist, so I don't actually believe there's gonna be a big change (if any) thanks to my vote, but still I would like to give it a try. The problem is, that in my country (Czech Republic), there's no, not even decent, socialist party :( Wanted to vote for Greens, but they moved so much to the center, that I don't wanna anymore. The Communist Party of Bohemia and Moravia is made of old people, who for me don't impersonate the future. They also don't renounce many of the flaws the previous socialist regime had and they're overall political dinosaurs :/ That's pretty much for the real left here :( I don't consider Social Democrats to be leftists... Eventually gonna probably vote for The Pirate party, that is not in fact leftist, yet has a lot of young people and nice plans about transparency and so on, which is kinda important to me. Who would you suggest? Should I start my own political party? I would definitely get some support from my leftist school mates :D Thank you for your time and I wish you a nice day :) Sorry for the long post though :/
