Halo96

The best keyboard for Starcraft is Nuphy Halo. Clem and Cure use it. It's good because there are no gaps between the function keys. 

I don't think that fits in your criteria in term of switch and/or size but I had a Nuphy wireless before and it worked with no issue at all (although the battery on it isn't great, had to charge it like every week, sometimes more). I've switched to an 8bitdo keyboard now, same, works no issue out of the box but this one has a beast of a battery...I think I've charged it maybe 4 times? And I bought it in october last year.

MX keys mechanical is good if you want a low profile board. I tried nuphy and really wanted to like it but it wasn’t for me. Still would recommend, it was very high quality and a very nice keyboard, we just weren’t a match. My daily drivers now are a royal kludge S98 for my work computer, and their southpaw version L98 for my personal computer. The pros are it was the only mechanical southpaw I could find that was reasonably priced, cons are that it doesn’t play well with Mac’s.

Buy a hall effect kb instead. They are both better and quieter. I have an Mchose for work and a nuphy for gaming. Both are far better than my logitech and razer mechanicals. I tried going back and it was horrible.
