What makes a good proxy Prioritize readability: correct name/mana/cost, clean rules text, and art that doesnt muddy the frame
Between these threats and more complicated kinds of value engine, discard decks are able to successfully leverage an uneven war of attrition and tempo: drawing enough cheap spells to continuously trade for and neutralise the opponents draws, while also grinding steadily towards a more permanent victory

The regular foil keeps getting tanked, but there is one version I dont hate financially
