Notes & Combos
Main goal is to get as much "dry powder" from deck into the graveyard. I used to run more monsters, but they just clog your Reasoning discard potential. Zombie world at 3 seems to be needed as opposed to 2 coppies as it often gets discarded in the process. Goal of the deck is to have rotating Eldlich and Balerdroch which will make it impossible for your opponent to play. Cards such as Gozen Match or Rivalry of Warlords are solid options, but for climbing ranked if find them too specific in current meta.
When you get Uni Zombie in first hand you can almost always get Bareldroch + Zombie World or Baronne de Fleur on the board on your first turn, just make sure to do the right combo.
When playing vs. Eldlich with Gozen Match it is better to keep Balerdroch on the field and discard Eldlich, than use Balerdroch to bannish opponents Eldlich and you can get rid of the Gozen Match with your Eldlich from graveyard (send from GY to hand and from hand to GY); it might seem wasteful, but you already couldn't summon anything with Eldlich archetype spells/traps so you will have enough of them ready to be send to graveyard.
Keep in mind that as with any 60 card deck, you sacrifice a bit of consistency for more overall power.
