Paulo, Nature Tamer

Whenever a non-token creature or a land enters
the battlefield under an opponent's control create
a 1/1 blue bird creature token with flying.
Whenever you draw a card, except for the first
card you draw on each of your draw steps you may
have target opponent gain control of a bird you
control.
Whenever a bird an opponent controls attacks
you, create a 2/2 green wolf token.
