The Infamous Becky

Haste, indestructible, trample, protection from
permanents and spells with men in their artwork.
When Becky enters the battlefield, exile Robusco
the Awesome. When Becky leaves the battlefield,
return Robusco to the battlefield.
Becky attacks each turn if able, and she attacks an
opponent at random.
At the end of your turn, shuffle Becky into your
library.
