Whenever Parhelion II attacks, create two 4/4 white Angel creature tokens with flying and vigilance that are attacking.
Crew 4 (Tap any number of creatures you control with total power 4 or more: This Vehicle becomes an artifact creature until end of turn.)
You choose which players or planeswalkers the two tokens are attacking. They don’t have to be attacking the same player or planeswalker that Parhelion II is attacking, and they can each be attacking different players and/or planeswalkers.
Although the tokens are attacking, they were never declared as attacking creatures (for the purposes of abilities that trigger whenever a creature attacks, for example).
