Destroy target artifact or enchantment. If its mana value is 2 or less, create a 1/1 black and green Pest creature token with “When this creature dies, you gain 1 life.”
For pest keepers, there's no sound more disheartening than breaking glass.
If the artifact or enchantment is an illegal target as Containment Breach tries to resolve, it won't resolve and none of its effects will happen. You won't create a Pest.

If Containment Breach resolves, and the target artifact has a mana value of 2 or less, but it wasn't destroyed (perhaps because it has indestructible), you will still create a Pest.

Although you may want to include Lessons in your sideboard if you're playing with cards that instruct you to learn, Lesson cards can be included in your main deck like other instant or sorcery cards.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
