Baz, Scrupulous Artificer

Other players can't cast spells during your turn.
At the beginning of each end step, if you didn't
cast any spells this turn, create an X/X colorless Careful Construct artifact creature token with lifelink, where X is the number of spells cast this
turn.
{w}{w}{w}, Sacrifice a Careful Construct: Baz gains protection from the color of your choice
until end of turn.
