In our Round 1 Feature Match Caleb Cosby used his Tribute Stun deck to easily take down a Shaddoll Artifact deck, and afterwards I couldn't help myself but ask him about his sweet strategy. "It's the definition of degenerate" is what he told me, but it's hard to argue against that when there's $10,000 on the line. His deck aims to totally lock his Shaddoll and Burning Abyss opponents out of the game with his Majesty's Fiend, Vanity's Fiend, and Royal Decree. It's a strategy we saw way back at the European WCQ, piloted by Luis Cossio, but haven't really seen it since.

Don't be fooled, though, because Cosby's taken a different spin on it entirely. While Cossio ran Archlord Kristya, Mausoleum of the Emperor, and Photon Sanctuary, Cosby's focusing more on the single tribute monsters. Cards like Fiend's Sanctuary and Caius the Shadow Monarch make Cosby's deck more effective at consistently putting out tributes and also dealing with fielded threats. One of the issues with Cossio's build was that it couldn't get over monsters with 2900 ATK very well, but Caius almost entirely solves that problem.

Even cooler? Cosby's running several March of the Monarchs, a card that literally nobody is playing but is actually amazing. Whenever it's on the field Tribute Summoned monsters can't be targeted or destroyed by card effects, making Vanity's Fiend and Majesty's Fiend virtually impossible to get over. Backed by Royal Decree, Cosby can form fields that his opponents can't get over, and then he can ride that to victory. That strategy proved effective in our Round 1 Feature Match, and I'd imagine it'll be great throughout the day.

DECKID= 101292Cosby also wanted to point out just how consistent his deck was. With Cardcar D, Pot of Duality, and Upstart Goblin he can almost always find a way to his lockdowns. Royal Decree is obviously ridiculous right now, shutting down the many chainable traps of Burning Abyss. However, Cosby's still got plays without the Decree because March of the Monarchs is basically three more copies of it, but that also stop monster effects and spells, too. He's built his deck to do one thing and one thing only, and that's make sure his opponents can't play cards. We'll have to see if that pays off in the later rounds!
