What is this glitch now?

Hello brawlers, now I have got thrown glitch after bug after glitch on me for the last little time, but nothing beats this. This. This, is all kinds of weird.

So as most of you guys know doing /war buy armor gives you iron boots and chestplate for one game. You can't say that this guy did /war buy armor because he had also iron leggings...

What am I talking about, you might ask. Well yesterday I saw this guy named dotti8000, just a normal war nonprestige player. I didn't really come in to a fight with him, until he starts complaining why he only has a diamond sword in his hotbar. I ask if he had bought superknife from the donation store and he said no. Keep in mind, he complained why he ONLY had a diamond sword in his hotbar, no guns. After a round he came on the opposite team, and I saw that he had iron leggings, boots and chestplate. He kept on having this every game, and I am pretty sure he also had a speed buff, cause he looked like running really fast. Unluckily I didn't get a screenshot of him, but it was very weird since this glitch/bug seemed so made up. Like it wasn't a fault in the plugins but rather something made on purpose. What I thought was that a 2.0 plugin accidently put on a killstreak for him, where he had these things, since it looked like he had the maniac killstreak from some CoD games. I don't know what this is, but I really want to find out! Do you, my fellow brawlers, know what this is?
