This page works by analyzing recent top decks from the past few weeks, automatically accounting for any changes to the Forbidden/Limited List and Tier List. Only cards which are used in those decks above a certain "usage threshold rate" are counted on this page, so the cards you see above are guaranteed to have been successful in multiple top decks from multiple players.
A "staple" card is classified as any card which is commonly used in multiple top-tier decks. Cards may shift from being staples to being classified as "archetype-specific support" if all but one of the decks using that card fall off the Tier List. Similarly, cards may become staples as other decks that use the card are promoted on to the Tier List.
The recommended deck is the best, most accessible deck on the Tier List, perfect for new or returning players. The price of each deck is estimated by looking at the "core" cards and then factoring in how expensive common "tech" cards are. If you're instead looking for information on one of the non-recommended decks, the deck-type pages have full statistical breakdowns of the cards used in every deck.
