This means that every card thats legal in Commander can be used in your deck
Commander Deck includes 1 deck of 100 Magic cards (98 nonfoil cards and 2 Traditional Foil Borderless Legendary cards), 10 Archenemy 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 Life Wheel, 1 strategy insert, and 1 reference card.
In that format, Spider-Man enables an interesting tempo-driven deck that taps, quite literally, into underused synergies from the past
it means you can get lots of extra mana if the creature generates mana, attack with abandon because youll be able to defend and, if your creatures have activated abilities, youll get to use them more
Tatyova, Benthic Druid is an example of this
These ever changing formats dont allow you to rely on professionals to build your decks for you, they make you do all the work
