I dont know which clan is better.help me list some advantages of each pls.thx

all clans are good , depends on the individual

I like nova grappler better.... raw powaaaaaaaaa... but dragonic overlord is good also XD

Kagero is mainly Power/Card Destroyer type of deck, it focus on retiring the rear guard of opponent while increasing power of key unit.

Nova Grappler is super irritating stand-up strategy, if you like to make your opponent crazy use this deck.
