Minecraft Smoke Wars! Deadly Smoke, Sumo Battles, Enchanted Steak and Much More!

I came up with this idea of smoke wars while trying to make a smoke that slowly killed you but accidentally made it an instant kill and it became the most deadly smoke ever!

Commands Used

Deadly Smoke: /summon AreaEffectCloud ~ ~1 ~ {Particle:smoke,ReapplicationDelay:8,Radius:3f,Duration:5000000,DurationOnUse:20f,Effects:[{Id:7,Amplifier:10,Duration:100,ShowParticles:0b},{Id:19,Amplifier:5,Duration:100,ShowParticles:0b},{Id:20,Amplifier:5,Duration:100,ShowParticles:0b}]}

Healing Bubbles: /summon AreaEffectCloud ~ ~1 ~ {Particle:bubble,ReapplicationDelay:8,Radius:3f,Duration:5000000,DurationOnUse:20f,Color:16711680,Effects:[{Id:10,Amplifier:4,Duration:40,ShowParticles:0b},{Id:23,Amplifier:3,Duration:20,ShowParticles:0b}]}

Knockback 1 Steak: /give @p minecraft:cooked_beef 1 0 {ench:[{id:19,lvl:1}]}

Change the 1 at the very end of the command to increase the power of the knockback.
