I’ve been doing daily Mystery Gifts on my gen 2 carts + Stadium 2 for the better part of six months for… fun? Something. Anyway, this experience has raised some questions that don’t seem to have answers anywhere.
My understanding is that the items/decorations which your save is able to send through Mystery Gift are determined by your ID number. bayleef’s thread "Mystery Gift: Reverse Engineering of IR Protocol" has a handy tool for figuring out what gifts you can send.
My hypothesis is that Stadium 2 mimics your GSC save’s ID in regards to what items it can send, and in ~500 Mystery Gifts, I found this to be true… with one exception! The day after my Crystal save (ID: 62000) sent a Big Lapras Doll to Stadium 2 (which prompted Carrie to freak out), I received a Magikarp Doll from Stadium 2 (which neither my Crystal nor any of my other GSC saves are capable of sending). Were these events actually related or did I just get lucky? Magikarp Doll is a common decoration to my knowledge, so it seems like I would’ve received one earlier if there wasn’t something to this.
How does Stadium 2 Mystery Gift work?
Does Carrie send you special loot if you sent her an uber rare item the previous day?
Are there special conditions for the three Stadium 2-exclusive decorations to be sent?
How rare is all of this stuff actually?
Any other fun GSC/Stadium 2 Mystery Gift trivia/anecdotes are appreciated.
(I apologize if this is actually all well documented somewhere. If someone could point me in the right direction, I'd be grateful!)
