Why did they leave out the green mascots? I'm so confused lol
Likely space issues. Adding a Fractal would have required adding a whole extra line or two defining how many counters to put on it, and adding a Pest would have required an extra line or more for the death trigger ability. Considering it took them 4 lines for just the 3 simplest tokens, adding the other two would likely have doubled the number of lines or more, for relatively little gain.
