Nick, the Dedicated

As Nick enters the battlefield, choose a creature
type.
Other creatures you control of the chosen type
get +1/+1.
Whenever a creature of the chosen type dies,
you may draw a card.
{b}{b}{b}, Exile Nick: Put a creature card of the
chosen type from your hand onto the battlefield.
Nick's power and toughness are each equal to the
number of creatures of the chosen type on the
battlefield.
