Earthbound OTK ft. Wights

This deck utilizes Immortal Dragon plus the "Wight" line for a little added consistency. The goal is to normal summon an Earthbound Immortal with Greater Linewalker on the field to setup for a direct attack OTK from the summoned Immortal.

Combo Explanation:
If Earthbound Prisoner Ground Keeper is normal summoned, you can special summon a Stone Sweeper. From here, you synchro Immortal Dragon. Use Immortal Dragon's effect to send Wightbaking to GY. Wightbaking adds Wightlord and Wightprince from deck to hand. Discard the Wightprince. Activate it to send Skull Servant and Lady in Wight. You can now use the Wightlord in hand to mill 5 cards by sending it to the GY. (This gives you a chance of getting Earthbound Fusion and/or a Greater Linewalker in the GY). Next, you can use Wightlord to summon Lady in Wight from the GY and use Wightprince to summon a King of the Skull Servants from deck.
At this point, you can look to go into any of the other synchro monsters using Immortal Dragon and the Wights on field as material: Diabell gets you a spell from GY, Accel Stardust can get back the Ground Keeper for Crocodragon draw, and Geo Gryphon can special summon back a Greater Linewalker/Prisoner Line Walker/Ground Keeper to continue setup.

Additional Notes:
- If you have the chance to get a Harmonic Synchro fusion use, use it. Geo Kraken can get you the Earthbound Prison for the extra normal summon of an Earthbound Immortal.
- Ultra Polymerization after the normal summon of a Ground Keeper (special summoning Prisoner Line Walker) can get you a search with Gremlina or Kraken.
- Double Wild will get you a Ccapac Apu in hand when used on any of the other Earthbound monsters. Ideally this gets you to a Greater Linewalker summon with Red Nova or just free summon from hand off directly from the Double Wild.
- Opening a Wightbaking or Wightprince and linking into Reliquished Anima can start an engine, but it's not ideal.
- Eldlitch is in the deck in case you open a Double Wild with one of the Wight cards and nothing else. It's not ideal, but it's something.
