Thermite Core

 is a cheap unit  which helps with offensive finesse.

Strategy
Thermite Core allows players to store a small amount of Attack between turns as Pixies. Storing the damage in this manner can help attacking more effectively when additional attack would be absorbed by a non-fragile blocker anyway.

Due to its very low cost, Thermite Core can generally be bought with leftover blue much like one would buy a Pixie. Again, because it is so cheap, even if it is not used even once over its Lifespan, it's not a huge loss, and sometimes the small value gained by saving one  for later can turn out to be significant over the course of a macro game.
