For LWW, we currently delve into Blade as Kenzaki and Friends battle the Undead. And one Rider, Chalice, wields the Spirit Human card.

Now SPOILERS AHEAD, the Human Undead card is never scanned like other Rouze Cards. It's only scanned on Chalice's belt and he uses it to de-henshin (among other spoilerific things).

It has never had it's power officially stated, so while we watch the Two of Hearts be an important plot point in Blade, let's theorize it's unique power.

I think it's shape-shifting.
