How many cards should an MTG deck have?

A standard constructed deck is a minimum of 60 cards; most players run exactly 60. Commander decks are 100 cards.

How many lands should I run in a 60-card deck?

Around 17–18 lands for an aggressive low-curve deck and 24–26 for a higher-curve midrange or control deck; ~24 is a safe starting point.

Up to 4 copies of any card except basic lands, of which you can run any number.

A beginner-friendly framework for building your first Magic: The Gathering deck — colors, the 60-card structure and the mana base.

Start small. A focused one- or two-color deck is far more consistent than a flashy five-color pile, because it lets you cast your spells on time.

Choose colors whose playstyle you enjoy: red and white push aggression, blue and black reward patience and control, green ramps into big threats.

A standard deck is 60 cards: roughly 24 lands, 16–20 creatures and 16–20 spells. Keep to 4 copies of your best cards so you draw them reliably.

Lower your average mana value if games feel slow — a curve that tops out around four or five mana is plenty for a first deck.
