Although these two cards don't have the human-shaped card tag, they are indeed human-shaped and can wear armor.
Moreover, both are giant cards. Could they have a little connection with the[Giant Sky Armor]?
Especially[Giant Zombie], which shares the same damage reduction mechanism as[Giant Sky Armor].
Ree Shil has also thought about attaching sword-type material to his Determination cards, making them sword cards.
But it has never been realized.
After all, he doesn't have many high-quality Determination cards.
For a Level A Determination Card, you need a Level A sword-type material card to attach a sword, so it's difficult to achieve.
One reason is that it's hard to find.
The second reason is even if you find one, it may not necessarily be compatible.
The third reason is that it's expensive. With that money, he'd rather buy a genuine Level A Material Card since he has a bunch of Level B cards waiting to be upgraded with gold edges.
