Shapeways - Especially Strangefate's store. Get the MotUC scale weapons as they'll work better. They're expensive, and you have to finish and paint em yourself, but they look really good when all fixed up.
Toybiz LotR - Mounts are a no brainer, they also have tons of bow/arrow sets, plenty of swords and shields and a lot of softer rubbery plastic robes and belts you can cut off and transplant onto ML figures.
ALL of McFarlane's stuff - Don't just limit yourself to the Dark Ages, Spawn figures from a wide variety of waves and sublines can have accessories perfect for these guys.
Funko figures - If you can find em cheap, you can scavenge a lot of stuff from them to re-purpose for ML figures. Maybe not weapons as much, but accessories like capes or soft rubbery armor bits are easy enough to remove and transplant.
Craft Stores - When in doubt, make your own stuff. Get thin leather lacing and straps, a good knife and some krazy glue and just go to two. Some good pliers and cheap metal jewelry chains can be used for all sorts of things.
These figures are great blank slates, you just gotta get creative.
>>5745941Right now, BBTS is your best bet. In a few weeks/month, a mid wave line up of four "new" figures, as well as a select amount of troop builders will hit the 4H shop so you can grab some of them. And not too later after that, a second mid-wave featuring more new figures, as well as a potential "All-Star" re-release is supposed to hit. It'll only be the top 10-ish or so figures, but that's still plenty to build a collection around. Come late fall/early winter a second full wave will launch on Kickstarter featuring females and elves, so you'll probably want to hop on that as well.
If you really want info, you should check the official Kickstarter Page,
Sourcehorsemen.com or the Four Horsemen's facebook page as anything new will be posted through those sources first.
