What's interesting about this is that it focuses on a relatively unexplored strategy: AI CC'ing creatures with Growth first. This means the Fire Spirits are free to burn throughout the entire duel. AI doesn't have enough CC to kill every creature, and so it kills some growables, but my Fire Spirits always stay safe. I know it's supposed to prioritize Growth over Ablaze, but man.
This is rather epic fail.
1 occasion I had a ~20atk fire spirit, and a newly played lava destroyer. AI bolts destroyer ???
