Wear // Tear and Serenity is for permanent-based hate cards like Leyline of the Void and Grafdiggers Cage (I like having a split as Serenity is better against artifact decks like 8-Cast but Wear // Tear is a more efficient answer specifically for hate cards), and Massacre is for white-based hatebears
Not so with instants and sorceries: They are, by design, single-use spells
Massacre Girl is basically a board wipe, and if youre into killing your own Creatures anyway, they might just be the best Commander for you
Review the change log after updates, keep an eye on new tournaments, and revisit your limits periodically
