The last iteration of ADP incorporated Galarian Moltres V, mainly to 1HKO the large amount of Shadow Rider Calyrex. While Galarian Zapdos V was of course for the Pikarom & Eternatus matchups, many players didn't fully understand just how good Zapdos could be in many matchups. Cobalion GX's inclusion isn't as straight forward, esspecially given that it's ability hardly ever came into play in this format, but to put it simply, its GX attack could be quite useful.
While less popular than its Shadow Rider counterpart, Ice Rider could still hit hard and fast with Melony and the Inteleon engine. The deck is quite straight forward, so it's pretty easy to pick up and play. You'll quickly realize that you're often hoping that Path to the Peak sticks, slowing down your opponent until Calyrex is ready to "stomp" hard.
This is Alex Schemanske's Urshifu deck that he took to a 1st Place finish in the 2021 Player's Cup IV. Many didn't expect to see Urshifu do well in this event, as the meta was swarmed with Shadow Rider Calyrex, but with Jirachi GX's help, Alex was able to spread big numbers with little threat of being outmatched by Psychic weakness.
This is the deck that truly dominated the short-lived TEU-CRE format. This deck was so common, that you'd more often than not play the mirror match multiple times per event. While most successful lists played the Alcramie V line with one Trevenant & Dusknoir GX, some lists incorporated a Cresselia from Chilling Reign. Or, just played multiple copies of Trevenant & Dusknoir GX in hopes of getting the hand lock each and every game.
Spiritomb was one of many decks that people always tried to make work, but it was just to weak and slow for each meta more often than not. Until, the Chilling Reign format. The deck quickly became one of the most feared decks, in an annoying way, because of how consistent it could be while only offering its opponents 1-prizers.
