Matchups are based on clan damage in prior Clashes, not wins and losses. 

That said at lower clan levels (and/or participation in said clans) I could see huge fluctuations in how much damage a clan could do on a week to week basis just because of how much those lower clans will improve just based on a few members improving comps, pulling and building better champs, etc.

Mmm ok so in theory we should always face clans about the same strength as we are, i thought there has to be some 500 iq move to lose 2 clashes a month or something along the lines, can just keep doing what we´re doing then i guess

Our c;lan was 1st to 3rd in the early days.  Now we are 5th.  We dont have any members with cadaver teams.  

Will Plarium make an announcement soon about cadaver teams? If they are here to stay we should know.  If they are going to be nerfed it should be done sooner, not later.  

Unfortunately Poly I just don't have a timeline to give you. I know it's something that Plarium is actively looking at but we don't know when it will be resolved. 

That's really just bs from Plarium though, when they want to do something they do it quickly, look at Inquisitor - how long did he last before the nerf came in, they even nerfed a champ before the actual release due to the CC's finding out he was to OP

If they haven't done something it's because they aren't that bothered not because they can't
