Eldlich Synchro to the full potential. Combo is just Halq + 1 extender, watch the video. If no extender (only Halq), we couldnt extend to the Drytron if we’re aiming for VFD. Summon Quandax instead of Arc Light, use Auroradon tribute 2 tokens, ss Coltwing+2tokens+001, make Shooting Riser dump lv1 to GY making Shooting Riser lv6, make Shenshen using Shooting Riser+token, make Trishula fusion using Auroradon+token+Coltwing, make VFD.
If you’re new to Eldlich playstyle, the goal is to have Scarlet/Eldlich + Huaqero/Conq on field. Cursed Eldland is the best for that since it searches Eldlich (extender for this specific version of deck) or Golden Land (Huaqero/Conq), it has GY eff to send Eldlich/Golden Land, super good because Golden Land GY eff can set Eldlixir (Scarlet) from deck.
Pros: Just regular Eldlich Synchro, but ultra powerful because Natasha+Shenshen follow-up.
Cons: Eldlich Synchro is not too good right now because fragile to handtrap and more bricks.
