For a minimum set: circular saw and guide, router, sabre saw, and hand drill. Plus the usual support items: tape measure, clamps (you can never have too many of those), sanding block, and an accurate square.

A better set would include a table saw, plate joiner, orbital sander, and drill press.

And that would be the order I would acquire them in. A skilled wood worker could add to that, but those are sufficient to build a basic scope.
