Joffi, Daring Racer

Whenever Joffi, Daring Racer crews a Vehicle,
that Vehicle gets +1/+1 for each other tapped nonartifact creature you control until end of turn.
At the beginning of each combat, Vehicles you
control gain first strike until end of turn if a
nonartifact creature you control has first strike.
The same is true for flying, deathtouch, double strike, haste, hexproof, indestructible, lifelink,
menace, reach, skulk, trample, and vigilance.
