yugioh fang of critias deck The Jaws [Custom Card] Lair of Darkness + Fang

During your opponent's turn (Quick Effect): You can banish monsters from your GY whose combined ATK equals exactly 2000 or 4000, then target 1 face-up card your opponent controls for every 2000 ATK of the total

Around half of the cards will be monsters, with the rest split between spell and trap cards

Snorlax acts as a tank, allowing you to safely evolve Meowscarada, while using Barry to get in some damage with Snorlax if you have extra energy

Meanwhile, Kelley was a talented but less experienced player, without a major event victory prior to reaching the Worlds final - and eventually taking the whole thing

Three "Ancient Leaf" can trigger "Spell Absorption" while also making use of the added life points for more draw power, three "Goblin Thief" are a dream card to use with "Fire Princess" due to supporting both the burn strategy via healing as well as inflicting damage on its own, three "Ledger of Legerdemain" can fetch more of the necessary cards via draw and the deck is able to stall enough to make that work, three "Swords of Revealing Light" are further stall options and also give a "Spell Absorption" trigger, two "Child's Play" help protecting "Fire Princess" while providing more healing for the "Cure Burn" strategy, three "Cauldron of the Old Man" provide constant healing/burning, three copies of "Dark Sanctuary" provide further protection while also inflicting damage, one "Terraforming" serves as a fourth draw for "Dark Sanctuary", one "Poison of the Old Man" serves as more healing/burning, one "Mystical Space Typhoon" against pesky backrow and one copy of "Magical Mallet" to shuffle unnecessary cards away while also providing another "Spell Absorption" tick

As with all TCG, it's luck of the draw.
