Ever heard of [Event] Noble Commander Card? This is what happens if you put together two parts of the same card.

They say that the left half of the card usually ends up as leftovers. I wonder why?

But hey, no worries! If you bring me 10 leftover [Event] Commander Card Left Half, then I'll take them and give you a little something in return.

Player: Accept.

I always enjoy puzzles and riddles! Did you bring me anything?

If you have some [Event] Commander Card Left Half, give them to me in units of 10!

Player: "Here they are."

10 cards! Great!

Here, take this. It's not much, but it should be more useful to you!
