how do i get her

Nice

I WANT ONE

So, when does she become available and how?

how and when does she appear

When and how can we get her?

Champ looks awesome but the lore is a little wonky. The Shadowkin faction has a lot of Japanese-style art and character names. Here you make a new, very Chinese-style character, with a Chinese name, but stick her in the Japanese faction as heir to one of the Sovereigns of Yakai, not a Chinese name at all. It's like you put her in this faction because she's Asian. But the two cultures are worlds apart from each other.

If anyone is curious, Shu Zhen cannot be translated to English directly without some more context or Chinese characters to dispel the ambiguity. Most likely referring to 梳针 comb needle or 树针 tree needle. But without tone markers or more information, there are many more possibilities for the translation to this name.

She is extrodinarily weak for a void lego.  The A2 that is supposed to grant an extra turn is just a turn meter fill.  And not granting the buffs and the extra turn when you remove the sheep just gets the champ killed.  It looks like she is targetted for arena, but her skills are polymorph bait.  I know you are trying to find ways to deal with sheep instead of just removing or reworking it(what should have happened in testing), but this isn't it.

how to acquire shu-zhen? Is there a way to buy the character directly?
