Editing Warhammer 40,000/9th Edition Tactics/Chaos Daemons (section)

===Pros===
*Armywide Daemon saves, armor saves that can't be modified, which makes them better than invuls.
*Wide range of miniatures, so painting never gets boring.
*Lots of different playstyles with 4 different gods, monsters, hordes, magic and so on. Probably even more once you factor in allying with the various flavors of CSM.
*Your Daemon Prince murder machines can hide behind other troops.
*Your army is completely compatible with Age of Sigmar, kill team, The Horus Heresy, Boarding Actions and, of course cause you're here, Warhammer 40K. It's almost like having five armies for the price of one.
*9th changes make Daemons fantastic at board control, lots of variety in objective holders and takers. When mixing Gods, you can oversaturate target priority, makes them stress about what to shoot.
*The entire army has all sorts of Deep Strike shenanigans which will work even when you ally with CSM, and all without needing to do summoning rolls.
*Warp Storms give you plenty of tricks to throw out-of-turn, including your most frequent means of shooting without needing guns.
