Notes & Combos

Playing Ritual Beasts has been a lot of fun again. I had originally planned to switch over to Memento, but with Emergency Teleport now being unlimited, I decided to give the deck one more month. Unfortunately, I'm starting to feel a bit burned out on it, so I'll be moving on to either Branded or Memento for next month. However, I'm not done with Ritual Beasts yet, since they'll be back for the next Duelist Cup!

As for the decklist, there haven’t been many changes since last time. The plan was to replace the Impermanences and Purges with Super Polymerization, but after running into Mermail Atlantean, that idea quickly got scrapped. I actually wrote a Python program to help optimize the deckbuilding process, and it showed that the version I used last season was already statistically strong. So in the end, only a couple of adjustments were needed:

  1. -1 Accesscode Talker || It didn’t come up often and was dead after using Dominus Purge from the hand.

  2. +1 Ritual Beast Ulti-Reirautari || Makes it easier to banish a second Ulti-Reirautari with Rampengu instead of the single Ulti-Gaiapelio. This keeps both the Nibiru combo lines as well as the Ulti-Gaiapelio itself available for the grind game. Just be mindful: if you go for Archnemeses Protos, you’ll have one less LIGHT monster in your GY to banish, meaning one of your two Spiritual Beast Tamer Laras will be banished instead.

  3. +1 Book of Eclipse || The 40-card build was consistent, but going second, I rarely saw enough handtraps or boardbreakers. Bumping the deck up to 41 cards lowered the odds of drawing a full combo hand by less than 1%, but increased the chance of drawing at least two handtraps/boardbreakers by roughly 3.5%. It also helps to dodge Effect Veiler, Infinite Impermanence, Primite Drillbeam and even Nibiru, the Primal Being.

It’s been a fun ride with you, dear Ritual Beasts. I hope you keep performing well - I’ll be back. 💫
