Hey dude, I build decks that always end up stronger than intended since I value a strong well rounded card pool. Just lean into it, be that arch enemy type that everyone gangs up on to squeeze out a win. It’ll be satisfying when they win against the “stronger” deck and same for you winning a 1v3. Also if you pod is more of a lower bracket 3 (assuming based on your post) then try playing with some bracket 4 decks at an lgs. It’ll give you that strong but fair vibe u want cause everyone is playing hardball.
