I see something like Davriel's Withering and immediately think of all the ways cards in my decks could be rendered completely useless if someone plays it well
You could discard it to pay a cost, because a spell or ability tells you to, or because you have too many cards in your hand during your cleanup step
All of these will have their own purpose, and some can be stronger than others depending on what youre looking for, so dont take the self-mill term too literally
That requires more creatures than a control deck chock full of board wipes
It's crucial to note this record-breaking sale was for a pristine, unsigned copy, deriving its value purely from its perfect condition and foundational rarity
This can have some interesting value in multiplayer games, but be careful to not boost up your opponents too much
