Have you ever built a deck and then hated how it played?

Just to preface this I’m super new to paper magic, and even newer to commander. I just recently finished building a simic landfall deck and after goldfishing to see how it played I immediately realized that I don’t like this style of deck. I had tried playing a version of this deck online, however I just realized how much playing online simplifies some aspect of the game that are quite a hindrance when you play on paper. The idea of playing multiple lands a turn like evolving wilds to get multiple landfall triggers was ok on paper, before I realize how much shuffling this requires on a singular turn (not a problem when arena thus the shuffling for you), thus making the deck feel like I’m playing solitaire but in bad way.

This was my 4th commander deck, so I still have some other stuff I can play. My main question is what should I do with the deck is this something I can fix by taking out some cards or should I just abandon that strategy all together and trade the pieces away to build something else. Has this happened to you before and what did you end up doing with the deck/cards. Interested to see what other people have experienced and how they dealt with the issue.
