^ ok thats very true but what im trying to say is that frozn has NO OTHER OPTIONS ATM and also kalindra is weak to ANY hindering abilities namely soa, sob, damage reduction. and revenge makes people slightly predictable.
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.
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.
