Jet Tengu

Flash, flying (This creature can't be blocked except
by creatures with flying and/or reach.)
When Jet Tengu enters the battlefield, you may search your library for a card named Mecha Tengu, reveal it, and put it into your hand. If
you search your library this way, shuffle it.
Whenever you have a card named Mecha Tengu
in your hand, you may play it for no cost. If you do, return Jet Tengu to your hand.
