Scour the Laboratory draws you cards equal to the number of instant and sorcery cards in your graveyard — in the right deck, that's easily five or more cards off a single spell. The seven-mana base cost is steep, but it drops to as little as two or three mana in a spell-heavy graveyard, which is exactly where you want to be when you need to reload.

Scour the Laboratory is a Commander card through and through — the format's longer games give you time to fill a graveyard and make the delve discount feel broken, and a six-or-seven card refill at instant speed can win a game on the spot. In Legacy and Vintage the competition is too stiff: Treasure Cruise and Dig Through Time do more for less in the same shell, and neither format rewards paying seven mana for a conditional draw. Modern and Pioneer have the same problem, plus the graveyard hate runs deeper and more consistently. Stick to Commander, and specifically to spell-heavy or graveyard-synergy builds where the discount is reliable by turn five or six.
