Aela, the Huntress

Whenever this creature enters the battlefield
or transforms into Aela, the Huntress, you may
have it deal damage equal to the number of
Forests you control to target creature.
When Aela, the Huntress deals combat damage
to a player, transform it at the beginning of the
next end step.

"If you wish to hunt with me, your feet need to be
quick, and your eyes quicker."
