It's obviously not perfect (like you said), but I think it's very accurate for the most part. For new players (or old players coming back after long absence), that list is a great starting point. The only clan I disagree with is Bangers.
All good ELO players should be able to spit out a list like that off the top of their head.
Don't give me too much slack, I only did that off the top of my head. Randal's probably the one I forgot, he is a very nice card I have to say.
Vermyn N's a good 4* Card, A 7 7 - 4 Opp Damage Minimum 1 is perfect for 50/50's and it can make people afraid to pill, 2 pillz on this bad boy and you got yourself 7 damage.
Depends what your natural pilling habits are like for the first comparison, I'll take Z3r0 D34d personally.
For the second one, it's really useful to have that + 3 pillz over the bonus it simply means you can pill more E.G Montana or Rescue Bonus is worse than + 3 pillz, if it was +2 pillz I reckon i'd go for Klawz.
Even against AS Klawz is quite weak so it doesn't really matter too much really. I'll take Staflhaust!
