summon your big boss multiple (king of the skull servant) create protection for it and put your skull servants and wight monsters into the grave to bost the damage of your boss monster, for the extra deck you can use linkuriboh and the fusion so keep them at 3, the rest are trash for the pot so keep them there, you can use other stuff that you have, you definitely won't want all the Dragonecro or linkuriboh to get banished , use the Dragonecro for OTK with your King since it make your opponent monster ATK 0 and summon a token to your field, use burial from the different dimension so you can return your skull servants, wight monsters to the graveyard after using there effect or the king's effect to reborn himself after be destroy by battle or card effects, you don't really need infinite impermanence but it's better to have a strong card in the deck but you should use pot as one of your main draw power
