MATHMECH Deck April 2025 | Yu-Gi-Oh! Master Duel

We’re BACK with more Yu-Gi-Oh! Master Duel online matches! This time, we're playing Mathmech—now taking center stage since Circular was recently unbanned in the TCG banlist (unrelated to Master Duel’s banlist, by the way). Last time, we used Mathmech as an extender for Code Talkers, but now they’re the stars of the show, climbing through links into powerful boss monsters.
