This is my current updated build of Trap Eldlich for February 2022, at this point I'm 99% comfortable and happy with the list even accounting for a potential Imperial Order ban. By no means do I believe Eldlich is a dead deck despite potentially losing a power 1-of, I think for a returning player or someone wanting to go from being "casual" to having a "locals" or potentially higher in certain metas level deck, this is an extremely safe deck to play, learn and get used to the game.
While not being Extra Deck reliant, you still definitely have the opportunity to access some real haymakers such as Zeus or Ningirsu and the sheer advantage engine granted by the natural progression of the game through using stuff like your Eldlixir of Scarlet Sanguine and Conquistador's graveyard effects really keep you going strong without a great deal of worry. However, one must take time with all decks like this to learn when to use their resources and maintain that advantage engine to avoid burning themselves out at the crucial moments of the game.
Edit: It appears Eldlich got even better than before.
