CDP: Earthbound with Dark World and D/D, ft. Dark Corridor & AC23 Support

Fiends, Synchros, Fusions, and more Fiends!


Strategic Summary:

Today’s extra Creative Deck Profile features the Earthbound archetype, bringing fun and joy to the world as they erupt from their lined prisons. The Earthbound theme originally debuted in the card game with just the Earthbound Immortal monsters, such as Earthbound Immortal Ccapac Apu; however, they were featured in the ARC-V anime as nostalgia bait a subtheme of Earthbound Prisoners and Earthbound servants to support their almighty masters. In AC23, we’re finally getting to see the card game versions of these monsters, and let’s start with Earthbound Prisoner Stone Sweeper (YGOrg Translation). It is the searcher for the theme, able to be discarded to tutor any Level 3 or lower Fiend Tuner, or you can just choose to Special Summon it if a card is in a Field Zone. As for what you will tutor with Sweeper, it will probably be Earthbound Prisoner Ground Keeper (YGOrg Translation), a Level 1 Tuner that Special Summons a Level 5 or lower Earthbound monster from your Deck or GY when summoned. The last new monster is Earthbound Prisoner Line Walker (YGOrg Translation), a Level 3 Tuner that tutors their Field Spell, Earthbound Prison (YGOrg Translation), or Harmonic Synchro Fusion (YGOrg Translation) on summon. Harmonic lets you Special Summon a Fusion and a Synchro monster from your Extra Deck at the same time using the same materials, which is a really neat option!

As far as your Extra Deck Earthbound monsters, let’s start with the big boss, Earthbound Servant Geo Grasha (YGOrg Translation). This Fusion monster is summoned using an Earthbound Fusion and an Earthbound Synchro, and it destroys all cards your opponent controls when an opponent’s monster is destroyed. Next up, Earthbound Servant Geo Kraken (YGOrg Translation) is the base Fusion option, tutoring any Field Spell when Special Summoned. As for the Synchros, Earthbound Servant Geo Gryphon (YGOrg Translation) gets to Special Summon an Earthbound monster from your GY as a Quick Effect, and Earthbound Servant Geo Gremlin (YGOrg Translation) has a Quick Effect that allows you to Fusion Summon an Earthbound during either Battle Phase. All things combined, these monsters can be quite effective; however, there just aren’t enough of them to support the Earthbound Immortal gameplan introduced by Earthbound Greater Linewalker. So that’s where I turned to two other Fiend themes to prepare more Tuners and Non-Tuners!

First up is the Dark World archetype. I’ve covered this plenty of times before on my channel; however, the Dark World theme got a major boost with the release (finally) of Dark Corridor (YGOrg Translation). This simple Spell tutors a Dark World, then makes you discard a card. Combined with the ease of access to a Field Spell in the form of The Gates of Dark World due to Genta, Gateman of Dark World, you have plenty of ways to get through your deck and access the Earthbound monsters you need. Also, Genta summons itself back, letting you Synchro ladder into your Earthbound Synchros as needed. And if there wasn’t enough synergy already, be sure to notice that Dark World Accession can be used to Fusion Summon your Earthbound Servants! The last engine is a D/D engine, featuring Dark Contract with the Gate, D/D Lamia, and a copy of D/D Gryphon. This engine gives your deck access to more Level 1 Tuners, and even more Fiends! Find your inner Harmony as Synchro and Fusion Fiends unite!

    Could you make salads with the new support?

      Hi there!

      I actually did already, it will be posted here to the site this weekend:

      This was made before Salamangreat of Fire, and definitely can use some optimization, but there’s a lot of cool stuff there in the new cards.
