Burla Braw, Titanslayer

When Burla Braw, Titanslayer enters the battlefield, you may put target creature on the
bottom of it's owners library. If you do, create a 1/1 Civilian creature token, exile it until Burla Braw
exits the battlefield, and Investigate.

Reach, Plainswalk, Hero (You may tap any number
of Civilian creatures you control to pay for that much
mana towards casting this creature.)
