Notes & Combos

Climbing to Master rank was really tough, but after failing for one season, I finally made it with Mathmech—even if it's only Master 5. I almost gave up!

This season's meta got even tougher with Fiendsmith turbocharging Snake-Eye decks, plus the constant threats from Tenpai and Tearlaments. At least next season's Beatrice ban will give us some breathing room.

Mathmech's greatest strength is its unbelievable consistency. With so many starter options, you can pull off devastating combos even with just a handtrap and single extender. The ideal 40-card build achieves perfect harmony between handtraps and engine pieces.

If you're new to Master Duel and want to climb efficiently, Mathmech is hands-down my top recommendation. Its combos are simple to learn but pack serious competitive power - the ideal training ground for mastering high-level play."*
