It's essay time rerer xD
Shuckle is nowhere near useless in battle, it's just your battle preference. Shuckle is more used as a pokemon that can setup rocks, and sticky webs. Shuckle is also one of the very few pokemon that has accessibility to sticky webs, and practically the only one that isn't a suicide lead. It can also start setting up shell smashes and be a pain for your opponent to take down. Overall, shuckle is a great pokemon to use although it Doesn't get recovery (Outside of Rest) or attacks to deal damage it's good at doing what it's supposed to do. Feel free to have your own opinion though

My most is disliked pokemon is... Fennekin. I don't think they really put in much with the design or origin for a starter that I dislike it. I don't not like it, no. I just think it's not as great compared to other choices.
