Sir Pudgepuff, the Brilliant

As long as you are making whirring noises, artifact spells you cast cost {1} less.
As long as you are holding a tool, you may cast artifact spells as though they had flash.
At the beginning of your upkeep, as long as you are holding a power tool, put two +1/+1 counters
on up to one target artifact creature unless an opponent pays 3 life.
