Strengths

Mastodons are a problem to answer — loaded with Combat Tech Marines they beat ground armies; load enough Marines and two or three Nightingales and air struggles too.
A free mid-game spike — Marines that survive the early game immediately occupy the Mastodons, so a won opening converts into a much stronger army at no extra cost.
Omega Team wins fights outright — three Spartans that hijack vehicles, inspire, and close games.
Stun chains create free kills — Victory Mine plus the Command Mantis drop, or Victory Turret on a hero, gives a window where the target cannot shoot back.

Weaknesses

The most expensive T1 hero upgrade — his opening hero investment is the largest in the game out of the gate, so a delayed or wasted hero hurts more.
The plan needs a won early game — Mastodons only spike if you still have Marines to put inside them.
Mastodons expire at Tech 3 — they fall off once Vultures exist, so the window you built toward closes.
Three dead slots on the wheel — Recon Training is among the weakest powers in the game, Time for Heroes stops mattering past 40 population, and Spartan Morale is skippable.

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.
