*Zhao Daiyu* is got 2 really good symbols Chaos/Evil. Void might be a really good splash for cards like Piegon Games, No Memories, etc. So it should be feasible to make a competitive deck with her, the only down fall is she is 6hs but she has 25 vitality. Lets break down her symbols.
Chaos Foundations: Lord of the Makai, Red Lotus, Oral Dead, King of Fighters 2006, Type-n Human, Destiny, Forethought, Anti K', Meat Eater, Billard Player, Kabukai Artist, Flames of the Fame, and Counter the Assault
Evil Foundations: Blood Runs True, Chester's Backing, Red Lotus, Oral Dead, Anti K', Meat Eater, Billard Player, Gorgeous Team, Revenant's Calling, the Ways of Punishment, Charismatic, A Beautiful Nightmare and Manifest Destiny.
Void Foundations: ***, Aquakinesis, Sakiyo-ryu, A Beautiful Nightmare, Shooting Cap and No Memories.
These aren't all of them, but some of the main ones. Seemingly Chaos/Evil is the way to go and the foundation base. Plus they mesh rather well together, like the Ibuki deck at GCC.
So the question is how would you build her?
I'm thinking about Chaos/Evil with a Heel Snipe and Ways of the Punishment teched in.
