lol I think the max I claimed at once was three, though I know I coulda got four on at least one occasion. Feelsbadman
Yeah however it'll work, seems like that's def gonna be the way to obtain the Legendaries, and it ain't gon be easy... especially if they do it by team, and then you need spares just so you can trade for the other ones.. like, if I can only get Moltres and you can only get Articuno..
My brother in law had an idea like they're waiting for a partner to do trading, like that partner's (like McDonald's or something) locations would become PokeCenters, and you go there to trade/heal or whatnot
