Banned Cards by Season
Starting Season 3, Chaos Zero Nightmare began removing certain cards from the Chaos drop pool for the entire season, because those cards gave too large an advantage against that season's theme. This page compiles exactly which cards have been confirmed banned.
Cards that are completely removed from the random drop pool in Chaos (and, starting Season 4, also in Zero System) for the duration of an active Galactic Disaster season, because they grant an advantage far beyond that season's balance theme. This mechanic only started from Season 3 onward.
Ban Table by Season
The Banned Cards rule only started from Season 3 — Season 1 and Season 2 didn't have this mechanic.
| Season | Banned cards | Note |
|---|---|---|
| Season 3 Theater of Illusion | Not yet announced | — |
| Season 4 Kaleidoscope Hatchery | Gear Bag Dream World | Also banned in Zero System |
The banned-card list is compiled from game update notes, cross-checked against multiple community wikis (source not named here). Any season the source doesn't list specific card names for is marked "not yet announced" — not guessed.

Gear Bag and Dream World. Both are removed from the drop pool in Chaos and in Zero System while Season 4's Galactic Disaster is active.
Season 1 and Season 2 didn't have the banned-cards mechanic at all. Season 3 was the first season it applied to, but the source hasn't published a specific list of cards for that season yet.
