2 rulings from Wizards of the Coast
- 18 February 2022Suit Up will overwrite any previous effects that set the creature or Vehicle's power and toughness to specific numbers. Effects that otherwise modify its power and toughness will still apply no matter when they took effect. The same is true for +1/+1 counters.
- 18 February 2022If Suit Up causes a Vehicle to become an artifact creature, it doesn't count as “crewing” that Vehicle for any ability that would trigger off of a Vehicle becoming crewed.
