Abe, Skywise Familiar

Whenever another creature with flying enters the battlefield, you may pay 1{g/u}{w/u}
If you do, create a token that is a copy of that creature, except it's a 1/1 blue and white bird illusion, it has flying and "when this creature becomes a target of spell or ability, sacrifice it."
Across the clouds I can see her fly
Out of the corner of my watering eye
