Supernova
The Supernova skill card (L · Anomaly · Active) in Gakuen Idolmaster: cost, effects and trigger mechanics during Produce. Picked up during a Produce run (lesson/audition/shop) — not tied to any single P-idol.
Card mechanics
Two different limit rules
Gakuen Idolmaster uses two SEPARATE limit mechanics for skill cards that are easy to confuse because both get called “limit”:
Supernova is affected by BOTH rules above: usable up to 1 time(s) per lesson, and only one copy is allowed per deck.
Card operations beyond regular upgrading
During a Produce run, skill cards are affected by several other operation mechanics — not just “upgrading to the + version”:
Takes one card out of your current deck. A removed card stays available in the reward pool and can return to the deck later through another effect.
Swaps a card you own for a RANDOM other card currently in the reward pool — you don't get to pick the replacement.
Like a random swap, but you get to CHOOSE which card to swap into from a small set of offered options — a rare mechanic that only appears in certain chapters/scenarios.
Discards all 3 card choices currently offered and draws a brand-new set of 3 from the reward pool.
Permanently removes one of the 3 offered card choices from the reward pool — that card won't be offered again for the rest of this Produce run.
Some Support Cards carry a passive effect: a chance to automatically bump the skill card you're using up one tier during a Lesson/exam/Audition — the odds depend on that Support Card's type, rarity and level.

Upgrade priority framework
Players commonly sort skill cards into one of four groups when deciding whether to spend resources upgrading them:
This page does not assign the card you're viewing to any group — compare its real effect and cost (the “Mechanics” section above) against the four criteria above to decide for yourself.
