As u can see there are a series of cards coming out..and sometimes you dont have to use em all...
Firstly, You think what clan to use...so whatever you use should have a combination of defence and offence or a combination of more
All Stars,sentinels,Uppers,Montana,Roots - offensive
La Junta,Fang Pi Clang,Pussycats-damaging and reducing damages
Sakrohm-plays a very good defense as well as defence such as cards like Uranus, GraksmxxT,SkrumxxT
Ulu Watu-also has huge damage and gives little reducing damage(Nanook,tanaereva,Gabrielle,Wee Lee)
Now u know what each clans do...as for some newbies they always try getting Fang Pi Clang/Pussycats which is bad for beginners...as u know for some players kv_ravendark uses good decks All Stars-Pussycats...as for 6sims-haji uses a Pussycats-Sakrohm(i dont know if he still use it)
So if u want to make ur good elo deck first u analyze which is which...so u make ur own combos and styles
