>>9661535Yeah, there are 1×2 plates with studs on both sides, get a handful of those just because they're unique.
Also while the mixel joints are great, you might wanna look at regular ball joints and sockets as well. And make sure you get all the parts for your Matoran hands if you're willing to try it, so you avoid having to double order.
Then look for black Technic pins, as the lego ones have gotten expensive. They have a variety of colours in axles, pins and connectors, just don't get overwhelmed and don't order everything at once because it's nice to have ;D
Everything else is up to you.
