New pendulum Doremichord has great grind game, together with Odd-Eyes and D/D consistency with its scale 0 making this deck a threat. Able to establish Simorgh Barrier Statue with Linkuriboh and Odd-Eyes Vortex Dragon to protect it, even the board is broken we will still have recursion from Cutea and Kepler (thanks to scale 0, we can pend summon them every turn), Vortex can recycle our scales and search it with Dark Contract with the Gate or Sky Iris. Combo is in the video, because most pendulum decks dont have linear combo.
Pros: Viable endboard and yes, best card is PENDULUMUCHO letsgoo
Cons: Pend is not the best deck.
