Wario's moveset needs to balance his moves that are from Wario Land and WarioWare more evenly. 90% of his moves are random and I don't think they even are from WarioWare. And Wario needs to have his SIGNATURE move we all know of, that one tackle thing from Wario Land as his side smash. That and for his grab attack he could shake the opponent repeatedly just like from Wario Land: Shake It.
