Maschiff are in South Province Area Two. Pawniard are in South Province Area Five. The best place to get Toedscool is East Province Area One - you can find them earlier but they're really rare. Finizen are in the sea near Levincia, but you can get them in the shallow water by the beach - you don't need to unlock Koraidon/Miraidon's swimming. Glimmet are in the caves in East Province Area Three, but are very rare. The others are near Glaseado Mountain/Medali. (Of course there's always the possibility of finding them in Tera Raids.)
Thank you both for your responses! Was hoping Greavard would be a bit more accessible early on but that doesn't seem to be the case. Will hope for a Tera Raid find or that someone can trade me one when I start playing which should be fine. At least the others seem reasonable (I think, still haven't sussed out how encounters work yet). Thank you both again!I'd like to add that you can find Greavard in South Province Area Six, though they are rare spawns, always accompanied by a Houndstone, and you can't get there until you've defeated all of the Titans, so depending on what you prioritize when you enter an area, you might be able to find Greavard there before Glaseado Mountain.
