My Build: Wario with Barrel Helmet, Trick Gloves, Shellfish Armor, and Shellfish Boots. Daisy with Barrel Helmet, Turbo Gloves, Cannon Plate, and Cannon Boots. Bowser with Turbo Helmet, Muscle Gauntlets, Turbo Pad, and Bushido Sandals. DK with Trick Helmet, Cannon Gloves, Cannon Plate, and Chain Boots. It may not be the best, but I have so much fun using it that I don't ever want to change it.
My teams been similar to this since starting, only changing it now going back to improve & make other teams 1. My Waluigi is the exact same more or less 2. My bowser has less speed than yours in exchange for more bulk & shooting 3. My Rosalina has max shooting over hybrid of that & technique 4. I don’t have daisy, early on it was a max speed toad & now a high speed & strength Pauline - I’ll definitely check Daisy out though thanks to this video
I’ve actually been using this team with almost the same exact builds. Knowing that you can do well online just means I need to work on the fundamentals more. Like I still can’t cross pass or team tackle well.
I think learning to shadow them with your defenders while baiting out dodges with charge tackle feints helped me most with this team. Doing the team tackles was something I started using after getting a feel for those things.
I feel like a great Bowser and Waluigi are essential to any good team build. Waluigi is just the best defender in the game and Bowser has an unrivaled stats layout that makes him the strongest heavy shooter. The other two players other than that I really feel like is a personal preference. My go-to shooter is actually Yoshi with a focus on shooting, passing, & speed. Having a good passing stat in a shooter feels really nice as it makes combo shots ridiculously easy.
