Demand for the promo card has been high in other countries, and although it is coming a week after the movie has launched in the USA, these promo cards could still move quickly
At Fair Game, we position Collector Boosters for what they are: a high-impact experience built for collectors and players who want the set at its most expressive and collectible form
Fill up on cheap creatures and token-makers then toss out a lot of targeting cantrips and buffs, like Ancestral Anger and Sudden Breakthrough
The card has diminishing returns, and its totally fine to play one, two, or three copies, if needed
Will it be one of the intended combinations, or something unexpected
Its obviously a much less powerful card overall, and you cant just throw it into a deck with no concern for what else is in there, but its possible there is a deck built with The Cauldron of Eternity in mind and then this deck could want Gray Merchant, but it really has to be a dedicated self-mill deck for it to work, because if you cast Gray Merchant and it dies naturally (which is the most common play pattern), it doesnt work with the Cauldron unless the Cauldron isnt on the battlefield yet
