Some switches that I've made from my last deck is adding Jowgen the spiritualist, Necrovalley, and Storming Mirror Force. Jowgen is a really good card if you happen to go second due to its effect to destroy all special summon cards on the field. Not only does it have this effect but it also stops special summoning on both sides of the field just like the barrier cards. Storming Mirror Force is a good card when you go second as well if they special summon all of their boss monsters turn 1. With storming Mirror Force you can send all of their attack position monsters back to the deck or hand. Storming Mirror Force also does not target so it plays around some effect monsters that would usually negate a activation if targeted. Last I have Necrovalley in here to mostly counter decks with graveyard effects such as eldlich. If Necrovalley is on the field and they cant get rid of it you practically win against eldlich. Everything else is basically the same as my last deck that I explained in my last decklist. Simple beatdown with negation of their spell ,traps, monster effects, and summoning. The extra deck is there for Pot of Extravagance so you can use whatever you want. Some cards you could replace is a couple necrovalleys becuase you could use Gravekeepers Commandment to search out the Necrovalley. You could also use Quaking Mirror Force if you would want to but I like Storming Mirror Force better. I would not recommend regular mirror force due to the fact that cards can be activated from the graveyard or when the monster is destroyed and sent to the graveyard. Hopefully this helps good luck!
