Just want to note that section #22 doesn't have a proper comparison:
You compare an effect that has a "to target" as part of the cost vs. an effect that has a "then" as part of the effect. While it's true that "to" has been dropped by modern PSCT, IMO it's more appropriate to compare an outdated "to target" as cost vs. a modern "then target" as cost (e.g. Tornado Dragon).
That section is pretty terrible, and depending on what it's trying to say, downright wrong
Not even going to touch on it until it's clarified, but either way that section is overcomplicated and deals with conjecture and hypotheticals that it has no reason to deal with in the first place. Depending on the intent of the second example, it's downright misinformation
Use "then target" rather than "to target". That's all there is to it
Targeting is not a cost
Yes, I see now that it makes no sense now, the example I gave you could activate the effect anyway, "then" in costs don't impact that at all, I have removed that part of the section completely.
Also, gonna view the new cards in Hidden Summoners later for my PSCT update thingy, just haven't gotten around to that one yet.
EDIT: Nothing worth noting in the Hidden Summoners, but Mayakashi Synchros all have the Cyberse Clock Dragon, so there you have it, it's now a common thing I guess.
