The Knight

Whenever you cast an insect spell, create a 1/1
colorless Swarm insect token with flying and
"Sacrifice this creature, add {c}."

{w}{u}{r}{g}: Put a +1/+1 counter on The Knight,
then search your library for a creature card with
mana value equal to or less than The Knight's
power, put that card onto the battlefield, then
shuffle.
