Seems like your views went down as soon as you started posting content outside of your usual niche of Minecraft content.
I don’t know anything about the algorithm but I feel like you disrupted who it sends your content to. Not everyone who likes Minecraft likes Pokémon and vice versa so it’s gone into a bit of frenzy, not knowing how to categorize your target audience anymore. But if you stay consistent over the course of the next 5-10 videos, sticking to one niche, it should be able to correct itself again. Focus on titles, descriptions, and tags using keywords to help it know who to push your content to.
