If you read pure clan topics

What pure clan brings the best quality to the table.

Zerg unit
Fatality
Eruption of pures
Corrupt pures
Redemption
Leet tatics
Sudden knock out
Bloody Vikings
Olympus
Supremacy
And to whoever I have missed . Sorry will add if spoken

I feel zerg unit is one of the best quality
Wise but lack the numbers. If they pulled 50, they could easily take down a clan with +10 on them

Fatality is obviously top dog until a real challenge is brought to them
