I both hate and love that ~50s American cars are so prevalent in Cuba from my understanding. Hate because it is/was out of necessity, love the enginuity required and that those beautiful cars are still taking people out for smiles.
I use the left for a layer change, middle and right are both space. I wanted to use the middle for another layer, but for many games I need to be able to reach space with my left hand while using mouse to the right.
Nuphy seems to be a well liked low profile keyboard manufacturer. They have several models out now so there's likely something that fits your needs. Not sure if they have ISO layouts though. If that's not an issue, you can always go full minimalism with a Corner or something similar.

I would just look through any number of online list of "Best Swarm Survivors". There's dozens of different themes and tweaks from the VS formula, including boat and train varieties!

He's literally the only streamer I've watched and I couldn't tell you why, his formula just works.
