For your speculative needs.
Some minor details about each theme in Deck Build Pack: Tactical Masters have been revealed by a promotional poster. The theme for which we still know nothing about reads:
Is this beautiful castle riddled with traps?
The princess’ tricks are always perfect!
“Shirogane no Shiro no Labrynth / Labrynth of the Silver Castle”

The comment about the set in general:
“Put your ingenuity to the test and clear (the game)!” (Kouryaku is generally just conquering, but it’s used in game strategy guides for clearing the game or a given challenge)
Mysterune:
“Challenge the mysteries of the world with runes! (as a reminder, the theme’s name is a pun on “mysteries”)
“Spring of the Mysterune”
Valiants:
“Stand in formation, o warriors!
Advance through the battlefield with that courage!!”
“Valiants Assemble – Mamonaka”
