Flying, deathtouch, lifelink

Whenever another nontoken creature you control dies, create a 1/1 black and green Insect creature token with flying and deathtouch.

Whenever one or more Insects you control attack, for each defending player, destroy up to one target artifact or enchantment that player controls with mana value X or less, where X is the number of attacking Insects you control.
