This definitely isn't the most powerful version of Eldlich, but it may be one of the best ways to play Mayakashi besides the Bone Tower FTK. the synergy between the two archetypes is fun, and it gives Mayakashi some appreciated disruption.
The Mayakashi engine is pretty straightforward, you want to use Hajun to summon Dakki and begin Synchro climbing to Gashadokuro, with Yuki Musume as an extender that can either start another ladder, or preferably help make the powerful Link 4 Yuki-Onna the Absolute Zero Mayakashi. She can make the ATK of a monster 0 and negate it's effects when a monster is summoned from, or an effect is activated in the GY up to twice per turn.
As for Eldlich, he provides a notorious advantage engine over the course of interrupting your opponent with soldiers of the Golden Land and summoning himself or other Zombies with the Eldlixirs, all of which float in the GY.
Cards such as Yuki-Musume can help get Golden Lord to the GY so you can SS him by his own effect. And the Scarlet and White Eldlixirs can revive any Zombie from the GY while Golden Lord is on the field, allowing you to summon your Mayakashi Synchros from the GY proactively to pop stuff, instead of waiting for your opponent to destroy the current one on the board.
The two archetypes are pretty easy to grasp on their own, and do not get in each others way. So I thought I would make a quick profile on it. I'm not a master of either of these two themes, so feel free to correct any misunderstanding I might have in the comments, or ask any other questions.
