Konami’s official article on the new Yosenju cards clarifies how to use them!
With regards to “Yosenju Saburoukaze”
“Place Face-Up into Spell & Trap Zone”
This effect does not “Activate” the card taken from the Deck, as it’s an effect that resolves by placing a card face-up on the field. Since it does not “Activate”, you do not have to handle the “activation condition” of “Dizzying Winds of Yosen Village” (i.e. “Activate this card only if you control a Level 6 or higher “Yosenju” monster.”) OR paying the cost of “Yosen Whirlwind” (i.e. “Activate this card by paying 800 LP.”)
With regards to “Yosenju Wind Ritual”
What is a ‘”Yosenju” Monster Card’?
A ‘”Yosenju” Monster Card” you control’ does not refer to strictly cards in the Monster Zone, it can count cards in the Pendulum Zone. This differs from a ‘”Yosenju” monster you control’ as in this case it refers to the original kind of “Card”.
