Chương 921: Chapter 326 A Level Breaking Balance Sword A Level A-40_2

If it was during the early/mid part of a card game, it might waste the opponent's chance to reveal a card once and delay their entire process of revealing cards.

Considering all factors, even if the [Breaking Balance Sword] could only use its skill once throughout the entire match, it would be worth it.

As for the second Material Card, it's a weird-looking capsule.

Unlike typical medicinal capsules, this thing is made entirely of metal.

Its surface also has electronic lines and traces of plate welding, which is clearly a mechanical capsule.

[Rhino King] and [A-39].

From the preview result of [Rhino King] and this Material Card, the answer can be found.
