A TCG press release confirms some archetype names, including the new Buster Blader-related archetype.
Shiranui is a confirmed name. What we had earlier as “Dynamist” is “Dinomist”, which is also perfectly valid. Twilight Ninja is also a confirmed name.
Finally, the Effect Monster Buster Blader is called: Buster Blader, the Destruction Swordmaster”, meaning what we had as “Dragonbane” is “Destruction Swordmaster”.
