Francisco, the Animal Tamer

Beast Bond
When Francisco, the Animal Tamer enters the battlefield, you may search your library for a creature card with power 3 or less and put it onto the battlefield tapped and attacking.
Tamer's Call
Whenever Francisco attacks, you may tap an untapped creature you control. If you do, put a +1/+1 counter on Francisco, and that creature gains trample until end of turn.
“With a voice that echoes through the wild and a heart in tune with nature, Francisco turns the untamed into loyal allies.”
