Whether you need to deal with a specific threat or clear the board, Damn is always a go-to card
Maybe it's a design decision.
This former $50 card was originally part of a five-card cycle from Guildpact, but weve actually seen LotV (wait, thats not Liliana of the Veil maybe abbreviating this card isnt the best idea) plenty, with reprints in Magic 2011 and Core Set 2020, before popping up again more recently in Time Spiral Remastered, Wilds of Eldraine: Enchanting Tales, and even Mystery Booster 2
Having more cards in hand gives you more options for how to play around and against your opponents, so most Commander decks have more than a little card draw as part of their strategy
The most obvious strategic change is that there's an entire extra deck and player that influence your decisions
Mesmeric Orb and Court of Cunning are two of the best self-mill enablers in the format
