thanks for the link to the jargon page and i did click the letters just didn't get that it was referring to that deck i thought it might be a card strategy and so was confused by the page it took me to
(didn't read the spoilers)
One possible strategy of the Deck "CCYB"
Step by step:
Play firefly queen and produce fireflies, accumulate fire quanta
Play Lava Destroyer, play Fractal on it
Use the accumulated Fire Quanta to play additional 5-7 Lava Destroyers, increasing your Damage output by additional 35-49
This strategy can be used in long games, where the opponent has lots of healing or is using spells like Miracle for the killing blow
CCYB doesnt rely on this, though. Its just an additional damage source for killing blows. Most of the time, the 4 damage of the fireflies themselves do the job. So upgrading the Queen is IMHO more about that 1 additional damage of the flies.
