For me, this is the best artifact in the format, and it’s not even close.
The number one spot is occupied by a worthy competitor, but Chalice is just too good to end up in second place. It is just such an impactful card, able to disrupt or shut down entire strategies, and it is great against a plethora of decks in the current format. Chalice on one is devastating for decks like Murktide, Hammertime, Death’s Shadow or Burn, while Chalice on zero turns off any Cascade shenanigans as well as a quick start from an affinity list.
Given its wide range of application, it is natural that it finds its way into most sideboards, except for decks that would suffer too much themselves by including it. The card is so good right now that Azorius Control even plays three copies(!) in their mainboard.
Chalice of the Void belongs to those unique cards from the past that would never be designed this way today. I’m thinking of cards like Ensnaring Bridge or Aether Vial, combining originality with raw power.
Chalice, additionally, is very well-placed in the current metagame and therefore should be the number one card on our list. Let us see what can be said about the card that our other authors thought deserved the top spot more.
