Ash Ketchum

Whenever a non-Human creature you control
attacks alone, exile cards from the top of your
library until you exile a non-Human creature
card whose mana value is less than or equal to the attacking creature's mana value. Put that creature
card onto the battlefield tapped and attacking,
then put the remaining exiled cards on the
bottom of your library in any order.
Humans you control have Exalted.
