Ok so this Deck, the second one from N/R Format. This Deck wasn't built by me I received a lot of help by some Discord users named Domnostein [Megalith Best Deck!] and Monk, The Local Ballpark Player (Yes this was in a N/R Format Discord Server).
This is a really budget Relinquished deck it's extremely cheap.
The objective is summoning Relinquished. For that you can use the Impcantation engine to speed up the strategy and making it more consistent, I completly forgot this engine so at first I was thinking of Djinn of Rituals Archetype and Sphere Kuriboh to try to have more options for the Deck.
The main weakness for this deck it's the fact that you NEED enemy monsters to kill your opponent, being Sonic Bird, Manju, and Senju your "Beaters" with 1400 ATK; so in the case you have your 3 copies of Relinquished in the GY and no way to recover it, that's GG; it's like an Pure Eldlitch having it's 3 copies of Eldlitch banished face down or absorbed by a Thousand Eyes Restricted.
After testing it out the best option it's going second. 'Cause your best combos ends with Relinquished and when you do that going first you hav in the best of cases 1 maybe 2 Relinquished with 1 or 2 Impcantation monster.
If you feel very brave you could try it out in Rankeds, you'll regret it very quickly.
Have fun. :3
