Thanks for the comments everyone!
1. I was worried about Fractal too when I made the card, but I figured that between its cost, the quanta types involved, and the fact that its a 0/1 creature, it wouldn't be too OP. Flood, Thunderstorm, Rain of Fire, and Plague would all work wonders here. I'm more worried that no one would use the unupgraded version since the upgraded one is much better. I might adjust the costs a bit, make the unupgraded a tad cheaper.
2. What do people think about the names? Are they too silly? I started thinking how the other cards in Elements have such neutral names while I threw in big adjectives. What about something like "Cloud of Insects" and "Swarm of Insects"?
3. I made another card to compliment this one,
