I recently tried out Skywars on the Lemon Cloud server and it was amazing. I'm attaching a link to a video I made of my game play with a friend. There is iron and diamond armor to get and there are very few glitches on this server. It's also really easy to get into a game on this server, so I definitely recommend it. Their server IP is play.lemoncloud.org. I have no direct affiliation with this server, just wanted to share that my friends and I really think it's awesome.
