Commander Decks Some Commander precons become valuable when they include strong exclusive cards, popular commanders, or sealed collector appeal
The extra card is usually Zuran Orb which gives you on the spot infinite life and mana but it can be Strip Mine which land locks your opponent quickly and hard
Many of its creatures are soldiers, clerics, and knights, and its spells focus on increasing the health and the attack of your minions (also known as buffs) or healing them (or yourself) instead
I dread to imagine a world where Urza was multiple colors when it's the worst to play against with just one
Aether Channeler, Sea Gate Oracle, Watcher of Tomorrow, Couldblazer, Augur of Bolas, and many more not only draw you extra cards, but in many cases let you take your pick of cards from the top of your deck
