1)Is Edo Fu any good?

2)How many seals to get her?Assuming 210 . I also see that you mentioned Edo Yagura ...So what are the mechanics of the treasure?Is it like GNW?Meaning that there 2 "super rares" and you get a random one spending X ss and the other one after another X

3)Yeah we all know that Edo Jin chars are not that good , but , what does time limited actually mean?After Feb 6 we kiss em goodbye forever and wait for the ninjas to appear in events OR are the time limited treasures are gonna be part of event cycles from now on?
