This Bloomburrow Peace Offering Commander Deck includes 1 deck of 100 Magic cards (3 Traditional Foil cards, 97 nonfoil cards), a 2-card Collector Booster Sample Pack (contains 1 Traditional Foil or nonfoil alt-border card of rarity Rare or higher and 1 Traditional Foil Uncommon card), 10 double-sided tokens, 1 deck box (can hold 100 sleeved cards), 1 strategy insert, and 1 reference card.
This doesn't mean a player is at risk of not having enough lands to build a functional deck, but that they need to be more careful when selecting lands for their decks to ensure they can reliably cast their spells 'on curve,' which roughly means "at the earliest point in the game possible." One method of determining how many lands of each type to include involves counting up the colored mana 'pips' on each of the non-land cards (found in the top right corner of each card's casting cost) and using those numbers to calculate how many 'sources' of each color a deck needs
