The value it generates as a 1-mana loot effect, drawing you two cards and letting you pitch two essential graveyard cards, with the option to flashback, is frankly insane
The mystery cards are usually 25 random common cards and 1 rare card, offering very little value
Online marketplaces like eBay, Whatnot, PWCC Marketplace, and Goldin Auctions typically offer the best prices for PSA-graded cards
According to Gavin Verhey , the reason, he believes, that there are four tokens generated by this card is because there were four members of the Strike Team at the time
For example, there are cards that, despite being heavily skewed toward defensive use, contribute significantly to win rates due to their high power level, making them well worth including even in aggressive decks (a prime example being Force of Negation, a counterspell that is difficult to use aggressively)
