As a Druid, you only spend hold to perform the animal form specific moves.  You can still perform your basic/class moves as effectively as your current form allows. 

From the class book: "You still use your normal stats but some moves may be harder to trigger—a housecat will find it hard to do battle with an ogre. The GM will also tell you one or more moves associated with your new form. Spend 1 hold to make that move. Once you’re out of hold, you return to your natural form. At any time, you may spend all your hold and revert to your natural form."
