I have chosen mostly (but not all) cards which are specifically good in all-Zombie decks, mostly (but not all) based on their potential in Commander, and mostly (but not all) with present day performance in mind rather than historic achievement
The MSRP for play boosters is consistent for each set and usually between $5 and $7 whether you get the 30-pack in Aetherdrift , an upcoming set, or the 36-pack booster box of Foundations
It worked so well in conjunction with Card not found and it was so good against the very prevalent control decks that it shut out other draw cards pretty well, although even those decks would sometimes add one Card not found or Card not found, because more cards is always more cards
The same is true for counters that change its power and/or toughness and effects that switch its power and toughness
There are also a bunch of transforming cards in case you're worried about the cards getting stale
Of course, players aren't limited to these starter decks and can build their own
