Main goal is getitng banshee in the graveyard while getting a tuner and another monster on the board to go into halqifibrax, into blossom, into linkuriboh into Balerdroch into Vampire Sucker on the first turn.
Optimally your first turn board will be Halqifibrax, Eldlich with conquistador set, Dragoon, ,Zombie world, with Vampire Sucker and balerdroch in the graveyard.
You go into Desert Locusts with Halqifibrax during your opponents main phase to make them discard a card then, if you get a level one on the board like dotscaper or millennium eyes restrict you can go into a spell/trap effect negate with the level 7 or if you use a Golden land you can go into the level 11 synchro with Halqifibrax which is alright.
Sometimes its better to have more monsters on the field then go into the synchro for Saryuja combos which will help to return the Red-eyes black dragon or dark magician back to the deck.
Extra deck is really tight the synchro set-up is all you can ask for from Halqifibrax, into Formula synchron (can miss the timing) or desert locust into the level 7.
Notes are I made this to be consistent with the banshee uni-zombie halqifibrax combo. Reasoning is particularly interesting in this deck because you run a lot of different level monsters with graveyard effects and the Eldlich traps get their searches causing you to potentially go plus 5 over all in card advantage.
Deck is very powerful and feels pretty good to play I've gotten 1157 Wins this Banlist with this deck and 415 losses.
