Where should I call the secret Denjuu?

[SM-dood(imported)]

I have the secret Denjuu's numbers already (actual cart came with the card with all of their numbers ... I'm waiting for the patch to become a little more complete, so Japanese it is for now :fungus: ). But, in what locations should I call/add them to make them most helpful, seeing as depending on where I call them, it will take longer for them to come to battle depending on where I go?
Sorry if that isn't explained well ^^;

Actually, secret Denjuu have fixed origins. Check out the table at the bottom of this page (it should be moved eventually)! So it doesn't matter when or where you call them.

Oh really? I could've sworn that they would originate from where you called them... thanks for that.
