Not only that given that your deck is actually smaller than usual you have only so many cards that actually impact something (remember we have 29 lands, Spiral, Uro etc.) you need space for cards that solve certain problems like Elspeth Conquers Death, Shatter the Sky, Narset, Parter of Veils and Dovins Veto and playing 4th Nissa instead of one of those often leads to games where all the cards are kinda clunky and one dimensional
