You are sooo wrong, kitkat. These are the actual Elo Tiers, according to my purely objective and absolutely non-biased scientific assessment:
22. Everyone else
Lol as said most clans are usable but some are just so bad.... namely frozn and berserk. Kalindra isnt even THAT good doesnt deserve a ban.
la junta is kinda underrated in my opinion if soa is not present they are quite threatening with cards such as naginata.
Oracle , Kalindra's beast .
8 power , 8 life gap with nothing added on .
Say you play Titsouk Azkyub Tiwi Ld many options , and lose . She turns into a ..
10 Powa 12 Life Gapping Beast .. + In fury and you got in 16 Life Gap and you'll probably spend 8 pillz in total (60 attack for Kalindra)
Personally I think that what you'd want to play is subjective to what's popular right now. After all, if everyone starts playing something annoying like Gheist you'd want to play a clan that can handle itself just fine against Gheist and still manage against the random half decks you'll see out there.
Sob doesn't hinder her too much
soa/dr does keep her in check, but most SOAs have 6 power (some rare 7, but most attack manip soa has 5 or less), meaning she can win with 4 pills easily. And since its +life/damage, DRs also have limited use depending on how low they can reduce damage. Naturally SOA-DRs shut her down real good, but SOA-DR is kinda limited and usually has really low power, so 1-2 pills for 2 damage? stil worth it imho.
There are many great clans if the cards are right, all are effective when you have the right cards and they are not banned. Clans like All Stars and Bangers are increasingly getting harder to defeat due to the releases of Saki and Beeboy, very annoying indeed. However some clans like La Junta just don't have the card to make them usable in ELO, cards like a Futoshi Ld should be released to combat these OP cards, especially for clans that need them.
