If I enter... I'm not sure. The only clans I've ever played were Falkow and Refess, the clan I have the most experience with is Refess but my findings with Refess is that they are the weakest clan so I'm not running them if I want to win but if I run any clan I'm not familiar with I'm also going to be at a big experience disadvantage against people running their natural clans.
Regardless of who I run, if I do enter, I'm not expecting to go far so I'll probably make my deck pretty wacky so I can have some fun with it.
The bunnies of Lavato have special abilities, like 'Action Skill: Make Carrot Disappear.'
