Bramasta Aji, Mech Exemplar

{r}{w}: Put a Tinker counter on target Vehicle you control. (Its crew cost is reduced by one for each
Tinker counter on it. If this effect would reduce its
crew cost to less than one, it becomes an artifact
creature instead.)
Whenever Bramasta Aji, Mech Exemplar crews a Vehicle, you may draw a card.
