Blog post coming soon. What is below comes from our tier-list notes until the full write-up is published.

Strengths

Cryotic Advances — the standout power on an otherwise thin wheel.
A better hero than Kinsano's — the Ice Cream Truck is the clearer of the two flame-and-freeze heroes.
Cryo Troopers over Hellbringers — the better of the two specialist infantry lines, and more fun to play.

Weaknesses

The kit has obvious holes — Kinsano gets Flame Hogs and there is no Frost Hog equivalent — the theme is not finished.
Only just above the worst leader — our ranking puts her a little bit better than Kinsano, and nothing more than that.

Cast frequency — how often players actually pick each power — needs the meta-stats powers query, which is the one tab with no Supabase rollup behind it. Left off deliberately so a leader page costs no D1 reads.
