In a toolbox deck, you run 1-2 of a large number of cards that all do different things, and then you run search cards (like this guy) to get those cards. By doing this, your deck becomes very flexible, able to do a bunch of different things without losing consistency thanks to the search cards.

The name comes from comparing the search cards to a toolbox - both contain a lot of different tools you can use, so you can always get whatever tool you need.
