Well every clan when it first starts war alot butnthen just dies so theres none rn maybe the new clan TH
And also beard and ae are warring currently and ye also glitch
Not sure who's the most active right now but Nitro played 62 wars within last 4 months and WAPOW had 58 wars in the same time period. Guess that kinda beats glitch's 9 wars total.
Error's been kinda active lately though, that is true (15 wars in past 8 days).
