I played heavily at kitchen table formats
Even putting cards back on top of the deck can help you control your draws and the flow of your game
Stoneforge Mystic no longer finds Colossus Hammer (or anything else), Archon of Cruelty is just a big flier and no longer wins the game for Creativity decks, Primeval Titan cant tutor up lands and gets blocked by Elesh Norn, Mother of Machines for days, Omnaths landfall ability doesnt trigger - the list of popular decks and cards that Elesh Norn stops is surprisingly long
If you really try, you could maybe say that Shadowbringers is about countering the end of the world, but thats really a stretch
Plus, like Haliya, only costing one mana isn't going to eat too much into what else you do in a turn
If there's a cost associated with having Ursine Monstrosity attack the chosen player, you aren't forced to pay that cost, so it doesn't have to attack that player in that case either
