At the North America World Championship Qualifier, Walter Jule uses a deck that was thought to be near dead by the meta to get 2nd place. Pendulums show that they can swing into action and prove they can still be relevant.
And since I've been doing this before, here we go into interesting techs or ratios with his deck profile for reference:
https://youtu.be/CP7K_HtpHc8
(1) ONLY 1 Black Fang and 1 Purple Poison Magicians - Walter states in his video that despite the 2 cards being good, they do not progress your game state, meaning that seeing them will not do anything for you and they can brick
(2) Magical Abductor - This card is good because it searches out your pendulum scales, and you will be activating spells often whether they are in the form of pendulum scales or staples, they will be there
(3) 1x Rescue Hamster - A good instant Metalfoes Electrumite, and it recovers 2 pendulums from your extra deck, allowing you to reserve on your resources, this card can be advantageous but can also brick, and is searchable via Metalfoes electrumite
(4) Cairngorgon, Antiluminescent Knight - This card is just really good for redirecting targeting which is pretty heavy this format at times, allowing you to keep key pieces on board
