5 Insane Little Engines That CRUSH Boards (And Are Completely Overlooked)

In this video, we’re breaking down 5 insane little go-second engines that can CRUSH full boards while only taking 7 card slots. These engines are completely overlooked in the current meta, but each one brings ridiculous value when you need to break through a strong opening field. We cover: • Fiendsmith – the tiny removal toolkit with sneaky recursion • Magistus – one Normal Summon that turns your Extra Deck into a weapon • Slime / Guardian Slime – free bodies, big walls, and surprise board-cracking lines • Tistina – bounce everything, reset the field, swing the tempo • Bystial Mini Engine – fast pressure and massive punishment for LIGHT/DARK decks Whether you’re a competitive player looking for efficient tech, or a casual duelist wanting strong go-second options without dedicating your whole deck, these mini engines deliver some of the strongest value packages in the game. 📌 Join the Discord   / discord   👍 Subscribe for more math-based Yu-Gi-Oh! strategy!    / @jessesstrategygaming   TAGS (SEO) yugioh go second engines, yugioh small engines, yugioh tech cards, fiendsmith engine, magistus engine, tistina engine, guardian slime engine, bystial engine, yugioh deckbuilding, yugioh meta 2025, yugioh go second tips, yugioh combos, yugioh overlooked cards, yugioh hidden tech, yugioh board breakers, master duel engines, jesse’s strategy gaming ‪@JessePerezStrategyGaming‬ #yugioh #masterduel #jesseperez #yugiohmasterduel #boardbreakers #fiendsmith #tistina #guardianslime #spenta #magistus #bystial
