MLB 2K10 Trading Cards: They Don't Unlock Classic Players

Trading cards in MLB 2K10 do not unlock classic players. They are a separate collectible meta-game.

What Cards Actually Do

• Earned by playing: Complete games, hit milestones, win online.
• Build decks: 20-card decks with players (current/legend).
• Card Challenges: Play mini-games (simulated) against CPU/online using your deck – win more cards.
• Bragging rights / collection: No gameplay advantage in main modes.

How to Actually Unlock Legends

• Franchise Mode: Sign free agents (legends appear in FA pool after certain years).
• Hall of Fame Challenge: Complete specific seasonal goals.
• In-Game Currency (VC): Purchase legend packs in "My Player" / "Franchise" store.
• Roster Updates / DLC: Some legends added via patches (2K servers dead now).

Cards = side activity. Legends = main mode progression.
