Jetta Vance, Spirit of Revolt

Skulk
Whenever a creature enters the battlefield, if it
shares a type with Jetta, you may search your
library for a rebel card with the same coverted
mana cost or less and put it into your hand. If you
do, shuffle your library.
Whenever Jetta attacks, you may put a Rebel
creature from your hand onto the battlefield
tapped and attacking.
