I think it could go a little different:
- Ha, I have a fractal pest deck, no mono or duo stands a chance against me! I'll defeat this aether player easily
- Ha, I have a fractal pest deck...
- <Plays a pest>
- <Fractals pest and plays a number of pests>
...
Ok, a 50% aether fractal pest might be a bit different, but it's certainly possible to make.
