Creature Warriors In One Command!!

Hello! Today (Or the past 3 days) I made this one command machine that spawns in mobs which are wearing diamond and have swords. While you cant see this its there. Put this command in a command block then tame the cat and dog to start it.

summon FallingSand ~ ~1 ~ {Block:stone,Time:1,Passengers:[{id:FallingSand,Block:redstone_block,Time:1,Passengers:{id:FallingSand,Block:activator_rail,Time:1,Passengers:{id:MinecartCommandBlock,Command:gamerule commandBlockOutput false},{id:MinecartCommandBlock,Command:"fill ~2 ~-3 ~ ~3 ~-2 ~1 stained_hardened_clay 8 hollow"},{id:MinecartCommandBlock,Command:"fill ~2 ~-2 ~ ~3 ~-3 ~1 stained_glass 11 replace stained_hardened_clay"},{id:MinecartCommandBlock,Command:"/summon Ozelot ~ ~5 ~ {HandItems:{id:diamond_sword},{id:diamond_sword}],ArmorItems:[{id:diamond_boots},{id:diamond_leggings},{id:diamond_chestplate},{id:diamond_helmet}],CustomName:Tank,CustomNameVisible:1,CatType:0}"},{id:MinecartCommandBlock,Command:"/summon Wolf ~ ~5 ~ {HandItems:[{id:diamond_sword},{id:diamond_sword}],ArmorItems:[{id:diamond_boots},{id:diamond_leggings},{id:diamond_chestplate},{id:diamond_helmet}],CustomName:Strongest Pup,CustomNameVisible:1}"},{id:MinecartCommandBlock,Command:"/summon VillagerGolem ~ ~5 ~ {HandItems:[{id:diamond_sword},{id:diamond_sword}],ArmorItems:[{id:diamond_boots},{id:diamond_leggings},{id:diamond_chestplate},{id:diamond_helmet}],CustomName:Better Than Before,CustomNameVisible:1}"},{id:MinecartCommandBlock,Command:"/give @p 64 fish"},{id:MinecartCommandBlock,Command:"/give @p 64 bone"},{id:MinecartCommandBlock,Command:setblock ~ ~ ~1 command_block 0 replace {Command:fill ~ ~-3 ~-1 ~ ~ ~ air}},{id:MinecartCommandBlock,Command:setblock ~ ~-1 ~1 redstone_block},{id:MinecartCommandBlock,Command:kill @e[type=MinecartCommandBlock,r=1]}]}]}]}
