Did you ever want to let your mobs you created naturally spawn all over the world? I've got EXACTLY what you've been looking for! All it takes is one command per mob, and one additional command for all of them...
Commands:
/entitydata @e[type=Zombie,rym=0,ry=10,tag=!found] {Custom NBT}
/scoreboard players tag @e add found
If anyone of you has a suggestion for future commandblock creations feel free to leave them in the comments!
