Oshikuru, the Sun-Ronin

Worship (Whenever this creature enters the battlefield
or attacks, you may sacrifice a nontoken creature.)
If a creature with flying was sacrificed with
Oshikuru's worship ability, Oshikuru has flying.
The same is true for all other keyword abilities.
Whenever you worship Oshikuru, the Sun-Ronin,
if it's legendary, create a token that's a copy of it, except the token isn't legendary.
