Recent decklists (MTGO Challenges & Leagues plus in-person events) running one or
more brand-new cards - a card whose first printing released in the past 45 days, or is still
upcoming (basic lands never count). It's the same test that marks new cards in every decklist,
so any deck flagged "N new" shows up here. The Decklists view is sorted by how many new cards each deck runs; the
Most played view ranks the new cards by how many decks registered them - click a card to
flip it and see which archetypes are playing it. New cards are shown
in green.
