Harmonic Prodigy
36% of games where Harmonic Prodigy resolved ended in a win for the caster, +12.7 percentage points above the baseline for decks where it stayed in the library, across 133 tracked participations.
Harmonic Prodigy sits in 4% of Commander decks tracked on Playgroup Live, a niche but deliberate slot claimed almost entirely by Wizard and Shaman tribal strategies. Its ability to double triggered abilities of those creature types makes it a force multiplier, not a standalone threat.
The cast win-rate signal is one of the stronger early reads in the dataset. At 36% wins in games where the card resolved, versus 24% in games where it never left the library, the +12.7-point gap is a consistent directional signal. Both sample sizes are large enough to take seriously, though the dataset is still growing and this should be read as a strong early indicator rather than a final verdict. Of drawn copies, 82% were cast before the game ended, with a median first-cast turn of 5.
The commander spread confirms the tribal home. Rootha, Mastering the Moment, Vivi Ornitier, and Kuja lead by raw deck count, but Gandalf, Party Guest and Rootha show the highest inclusion rates among commanders with meaningful sample sizes. This is a card that rewards building around it, not slotting in anywhere red appears.

First-cast turn
n=147The "good card" funnel
694 brought · 329 playersOf 694 Harmonic Prodigy copies brought to games, 180 were drawn, 147 of those were cast, and roughly half of resolved copies survived to the end of the game.
Players who cast this card win 36% of the time (n=133) , vs 24% when it never left the library (n=442).
When players drew this card but left it in hand, they won 35% (n=32) — about the same as leaving it in the library. Those players survived long enough to draw it, so the gap above is about the card resolving, not just about surviving.
Observed gap +12.7pp; 95% confidence interval +4.5pp to +20.9pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
Final zone distribution
