Butchered by the recent banlist, not even a month after their 2nd wave of support arrived, this formerly Tier 1 Deck fell off the face off the earth. "Purrely" was hit by the limiting of their best Spell, "Purrely Delicious Memory", which is especially egregious due to the archetype being able to reliably search it anymore, as before, you could reveal 3 copies of the same card to search out a Purrely card, but with only one copy, that drops from a guarantee to a 1 in 3 chance.
The goal of this deck remains the same however, build up materials on your little "Epurrely" Xyz monsters and make the big "Expurrely" Xyzs. "Expurrely Noir" is an unaffected Towers with a powerful removal effect, and "Expurrely Happiness" is a crazy OTK machine with an AoE negate effect. The Epurrely and Expurrely monsters get more powerful if they have one of the Main Deck Purrely monsters attached to them, and the Epurrelys are also able to attach more Purrely Memory Spells to themselves when one is used, allowing them to build up more material, and each one has a different effect when they do.
The deck did however recieve an alternative way to summon the best Epurrely, "Epurrely Plump", without using Delicious Memory, in "PurrelySharely!?", which allows you to target a Purrely Xyz you control, then Special Summon a Purrely monster from the Main Deck and use it to Xyz Summon a different Purrely Xyz with the same Rank. This new archetypal Trap is also easily accessible by their new Epurrely monster, "Epurrely Noir", which shares the same effect of the other Epurrely monsters to attach more material, but allows you to set a Purrely Trap from your deck when you do.
