you guys should check out CS:GO Multi-1v1
it's pretty fun and good practice
"CS:GO Multi-1v1 is game-mode similar to deathmatch on aim_maps. Each map has a number of arenas (at least 9) where players face off in personal 1v1's. At the end of the round (when each of the 1v1's are over), the winners advance up 1 arena, and the losers go down 1 arena.
Your goal is try to reach the top arena and keep fighting off the challengers!"
