a bait before main box contain xyz monster or better, structure deck for Yuma since when new world release the main protaginist always got a structure deck
You’ll be waiting a while for that main box. The first ones introducing the synchro era to DL were garbage. And the structure deck for Yusei was trash too unless you think that Junk Warrior is a good deck, which you might.
Yea, expect the structure deck to be themed after Gagaga.
Which is a good archetype, but they're not worthwhile to buy unless we have a lot of good generic Xyz as well. Gagaga is meant to be material fodder. What's the point if you can't use that fodder for anything worthwhile?
