Available at a big event by one of Konami’s partner stores.
Yu-Gi-Oh! Duel Monsters Half Deck LIGHT
Yu-Gi-Oh! Duel Monsters Half Deck DARK
These half Decks will be available at the Card Labo Trading Card Game Festival 2018 event. Size as well as contents are unknown. However, they aren’t for sale and are intended as Demonstration Decks for players, that will be given to them to keep after the demonstration.
It’s likely there should be no new cards, nor especially advanced cards. The last time these Decks showed up, they were basically extremely easy simple cards for kids and newbies to be introduced to as to avoid scaring them with too much information.
We’ll report their contents as made available, but keep in mind these are likely simple.
For reference, these is the contents of the previous Half Decks
