These are often delirium cards like Shifting Woodland, Dragon's Rage Channeler, and Demonic Counsel, though they also play nicely with Rendmaw, Creaking Nest
same goes for lands like Field of Ruin and Treasure Vault
A card might say, You may sacrifice a creature
In all fairness, the actual ability itself isn't very bizarre, but rather just the way it's phrased on the card
You can also win the game through commander damage
