What this list actually runs on: how cheaply it casts things, and whether it has enough ramp, card draw and interaction to keep up at the table. Each block is one card — hover for its name.

Counted from Scryfall’s community card tags, not from the builder’s own labels. A card that does two jobs counts twice, so these add up to more than the deck. The hatched band is a common rule of thumb, not a law — combo decks run leaner, battlecruiser decks heavier.
