The goal of the deck is to do the usual Eldlich grind strategy while also setting up a double monster wipe off of Battle Butler. Ideally you want to go first as this deck struggles pretty hard to break established boards, so your side deck should generally focus more on solving this problem if the many hand traps prove insufficient. You can get to a Butler off of any Prank-Kid, by doing as follows:
- Normal summon any Prank-kid, link into Meow-Meow (which summons a different Prank-Kid from the hand/deck)
- Link the Meow-Meow and that Prank-Kid into Bow-Wow-Bark (which summons a different kid)
- Link the Bow-Wow-Bark and that Prank-Kid into Dodo-Doodle-Doo, using its effect to search out Prank-Kids Pandemonium (and summoning a different Prank-kid from the deck
which MUST be either Fansies, Dropsies or Lampsies)
-Activate Dodo-Doodle-Doo, adding back the other two materials for Battle Butler from your GY to your hand
-At this point, with some combination of Fansies, Dropsies and Lampsies in your hand/on your field, activate Pandemonium to fuse all 3 into Battle Butler (which locks you into Prank-Kids for the rest of the turn, so you'll want to either summon your Eldlich the Golden Lord using his own effect first, or wait until your opponent's turn to summon him using Eldlixer of Scarlet Sanguine/White Destiny)
*Side note: when you mill a card for Fansies' effect, just send a copy of Prank-Kids Place since you won't be needing it at that point. Furthermore, make sure to not banish any Prank-Kids from your hand for Rocksies' effect as you need all 3 other Prank-Kids in play to make the Battle Butler.
Technically you can do this combo without Rocksies (instead just going Kid -> Meow-Meow + Kid -> Dodo + Kid -> Dodo effect to add back kids -> Pandemonium for Butler), but using Rocksies allows you to fix a dead handtrap in your hand (like Nibiru) and sets up an additional attribute in the GY for Accesscode Talker later.
Otherwise, this deck works just like your typical Eldlich affair, with Crystron Halqifibrax + Selene to get an easy Accesscode Talker turn 3/4 using Effect Veiler. The Extra Deck is extremely flexible beyond the Halq/Selene/Accesscode package and the Prank-Kids cards, so really you can run whatever you want (I opted here for several links to link away already-used Conquistadors and Huaqueros, but really you could run whatever you want). Furthermore, the Side Deck should obviously be tailored to fit your own personal preferences/needs.
Is this particular combination of decks any better than the countless other Eldlich mashups (Invoked, Dogmatika, etc.)? Probably not, as Prank-Kids are notoriously fragile and are countered by just about every hand trap currently played. That being said, the double Battle Butler wipe is certainly funny to pull off and can set you up for an easy grind/OTK later as your opponent struggles to get enough field presence to power through your Eldlich cards.
