What's a set from a game that is a must complete for you and for what reason?
I'll start, this set had arguably the most hype around it than any other set in Digimon.
I remember trying to pick up a box from my locals only to find out it was sold out in less than 3 hours, which is a first since the scene has been dominated by Magic and Yugioh since forever and the store had bought 2 cases of this which to this day it's considered too much when you take to account how many people play/buy Digimon here.
Great set for both players and collectors, especially the knights themselves who to this day have some kind of meta presence or collectors value.
