Agatha, Queen Amoung Insects

Insects, Spiders, and Pests you control have every keyword that an Insect, Spider, and Pest on the battlefield would have.

If Agatha would leave the battlefield, you may exile
an Insect you control, if you do. Agatha remains on the battlefield.

Agatha's power and toughness is equal the number
of Insects, Spiders and Pests you control.
