Pokémon

For some Arceus-forsaken reason, I have set upon myself the task of catching all the various forms of Pokémon available in Paldea (except Vivillon, fuck that. 😅) and that means getting my hands on an Antique Form Sinistea.

I've been hanging around Alfornada, catching every cuppa I cross paths with for... A while now. I have over three full boxes of Phony Sinistea. I realize now I could just check their little teacup booties for a sticker before bothering to catch them, so I can spend less money on repeat balls now.

But is there anything I should know about hunting this thing down? Are there areas it's more likely to spawn, or areas that it definitely won't spawn at all? I assume you can't breed Phony teacups to get an authentic Antique; will they show up in mass outbreaks? Is there any way to increase my odds of finding an Antique Sinistea? Do I just need to suck it up and keep grinding?
