Leaked new character
A mysterious character that was previously "leaked" and revealed from the datamine files. It's a character from the card D.D. Guide, similar the other two card characters in the game: Card Trader, who gives you cards in exchange for trader items, and Tour Bus From the Underworld, the one in charge of Duel Quiz.
What role does it play?
The image seems to suggest that it's a character that works like the card trader, but appears at the rightmost part of town, possibly with a different feature. Card crafting perhaps?
What is card crafting?
Other digital card games have features that allows you to craft cards that you want. Either by fusing multiple copies of cards, or by obtaining pieces/fragments to make a whole.
What is the clock icon?
Looking at the picture shown above, we can see that cards have timer icons on the top right of each cards, presumably indicating time left until they leave?
This will just upgrade cards to glossy or prismatic not to craft cards otherwise whats the point of buying packs or winning cards through duelist to obtain cards? F2P will be having an easy time making good decks if so
This was announced or hinted at way before Konami decided to (soon) give us the ability to upgrade our cards. Card Creation is likely to be just that: Using the useless amounts of Rare gems we have for something new. I actually really wish they'd let us sell them for Coins because I'm always out of Coins with no real way to get some fast besides some events.
I KNOW ALL THE THRUTH!
So , first of all it's D.D Guide and as you can see, D.D Guide "sell" only cards from discontinued packs. So it's probably a new NPC for people who missed the chance to get cards from other packs ! :)
