Thats because it heavily leverages the goad mechanic to get your rivals fighting each other, while also using cards like Propaganda to put them off of attacking you
With their towering HP values, spectacular full-art designs, and that notorious 3-Prize rule when a Mega ex is knocked out, these cards are already shaking up both the collector market and early deck-building experiments in Japan, and we expect the same to happen worldwide, too
This makes Adamancipator decks a reliable, consistent, and enduring choice for the meta
It can apply a tremendous amount of pressure because as your opponents health drops below half of their starting life total, Anya gets a +3/+3 bonus and becomes indestructible
Of course the bigger win here is that Preparation of Rites can be used since you have Level 7 Ritual options, giving you the ideal Spell to recur back from the GY with your new Dark Chaos Magician, since it gives you +1 in card advantage each time and doesnt have a hard Once-Per-Turn effect
