lets start off with the basics shall we do /give <player> coomand_block (Note: only works in 1.7)  its a lot like bedrock when it comes to breaking becouse you cant break it in survival. then choose on of these: @a all players @r Random players and @p nearest player! the cool thing is it works like just doing / (Note: it is in vannila minecraft.) but for some commands you have to use
not / here are some: summon Zombie (Or What ever you like) or say (What ever you say) or effect (What ever effect) you can do normal ones to but here is
how you arrange them: /@p Gamemode 1:  its good for a map so when you start it could say go over to the pig and then when your there you get slownnes.

the limts for effect is 0-23 dont try to go higher. its conted as redstone but not in the inventory (Creative) you must have cheats allowed to get it.
