Zombie world synchro deck! tips/advice please?

Zombie decks loves to abuse returns from the graveyard, so your biggest fear is probably a Dimensional Fissure or a Macro Cosmos. So be prepared for them. I personally have 2 Dimensional Fissures in my side deck just in case I'm facing Lightsworn or Zombies. I run a Gladiator Beast deck and they hardly every have monsters in the grave. So by me having 2 Compulsory Evacuation Device, 2 Thunder King Rai-Oh, 2 Dimensional Fissures, and 3 Solemn Judgments, your deck is screwed. I suggest having staples like MST and Heavy Storm in your deck. Also, have 3 Solemn Judgments to disrupt your opponents flow. Half your life points may be worth it in the end. Also, a or 2 Phoenix Wing Wind Blast would also be good to protect your zombies. Hoped this helped
