Ep 22. Unseen Enemy: Sea Stealth II.

In this episode of Yu-Gi-Oh Duel Monsters, titled "Unseen Enemy: Sea Stealth II," the duel between Yugi and Mako Tsunami continues. Yugi is still struggling to stay afloat on Mako's ocean playing field, while Mako seems to have the upper hand, given his unmatched skill as a fisherman and his ability to summon powerful water monsters.

As the duel goes on, it becomes clear that Mako has something up his sleeve - namely, a trap card known as "Sea Stealth II." This card allows him to hide any one of his monsters on his side of the playing field, making it impossible for Yugi to attack it directly. Furthermore, Mako also uses a powerful monster called "The Legendary Fisherman," which is immune to spells and traps, as well as Yugi's signature card, the Dark Magician.

Despite these setbacks, Yugi refuses to give up. He starts to think outside the box, coming up with creative strategies to take down Mako's monsters and whittle away at his life points. Along the way, he also learns a valuable lesson about the importance of patience and perseverance in the face of adversity.

Meanwhile, on the sidelines, Mokuba and Seto Kaiba continue to scheme. They sense that Yugi is in trouble and want to find a way to turn the tide of the duel in his favor. However, they soon realize that they may have underestimated Mako's skills as a duelist - and that he is a force to be reckoned with.

As the episode comes to a close, it seems that Yugi is on the brink of defeat. Mako has only a few life points left, while Yugi is hanging on by a thread. However, as always, Yugi finds a way to dig deep and come up with a winning strategy. Using a combination of his Dark Magician and other powerful monsters, as well as some clever spell and trap cards, he manages to turn the duel around and emerge victorious.

Overall, "Unseen Enemy: Sea Stealth II" is a thrilling episode that showcases the best of Yugi's dueling skills and his unbreakable spirit. It also sets the stage for more exciting battles to come, as Yugi and his friends continue on their journey to become the best duelists in the world.
