You must trash Tool cards from your GARAGE that have a total cost of $5 or more in order to sway this.
You may trash a single Tool as long as its cost is $5 or greater.
The Tools that you choose to trash must be in your GARAGE. You cannot trash Tools from your hand or YARD to pay this cost.
You can trash your starting Tools from your GARAGE to pay this cost. That may not be the best wisest way to spend an early turn, but you do you.
When scoring, this is worth 5 VP if it's in your Sway.
