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!
Individual valor means nothing, in any tcg, unless the card is really broken. There are "staple" cards that are shitty in certain decks. There are shitty individual cards that are totally broken in a certain types of deck.
