Explain How Competitive Card Game Deck Archetypes Work

Moving from casual to competitive card games is largely a shift in understanding why a deck is built the way it is, not just what the cards do. Archetype theory explains what your deck is trying to accomplish and how it interacts with other decks. Once you understand it, deckbuilding and matchup decisions start making sense.
