I made a couple of my basic ideas for cards into actual cards in order to be able to patch holes. One of the ones I thought of with this one was, as you said, fractal. Edit to prevent fractal abuse. Cannot be targeted by owner.
I'm pretty sure it's overpowered as-is, and I have a few ideas for how to nerf it. Examples:
-For each Wasp on your side of the field, Wasp has a 4% chance to miss. Elite Wasp has a 3% chance.
-Increase cost to 4 or 5.
-Wasp has a percentage chance of being lobotomized each turn.
Oi! What about its ability is spent upon use? That would mean only newly produced wasps can produce new wasps. This would slow it down significantly.
