Timelapse view of hornets constructing a nest. At one point during a camping trip when I was young one of my fellow hikers stepped on one of these. It did not go well for the humans.
A good illustration of spells vs. creatures; player A has a deck of only Forest and Hornet Sting, player B has a deck of only Mountain and Mons's Goblin Raiders. Both business cards cost one and deal one damage. But Mons's sticks around and that player is going to win the majority of those matchups. That's why the days of creatureless decks being a major force required spells to be much better than creatures.
