One More Step+
The One More Step+ skill card (SSR · Sense · Active) in Gakuen Idolmaster: cost, effects and trigger mechanics during Produce. Exclusive card of P-idol Shiun Seika — Tame-Lie-One-Step — only this P-idol brings this card into a Produce run.
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”:
One More Step+ 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.
Card customization
Customization options available when upgrading this card during Produce — each group has multiple levels, costing increasing P (customization points).
When a card is upgraded through MULTIPLE sources at once (customization + Support Card assistance, shown as ++/+++), how the bonuses combine depends on the effect type: different types stack freely; same-type stat boosts add their magnitudes directly; same-type cost reductions stack but can't go below 0; “add effect” entries of the same type can trigger TWICE even though the card art only shows the icon once.
On One More Step+ specifically, the available customization groups are: Add effect — if you upgrade several of them at once, apply the stacking rule above separately to EACH group.
Only the already-upgraded (+) version of a card — not the base version or a P-idol-exclusive version — can be customized. Max customization count scales with rarity: up to 3 for R, 2 for SR, 1 for SSR (with a few card-specific exceptions).

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.
