Rulings
One official ruling, as Wizards published it.
- 2024-07-26
Rat Colony's last ability lets you ignore only the "four-of" rule. It doesn't let you ignore format legality. For example, during a Bloomburrow Limited event, you can't add Rat Colonies from your personal collection.
Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.

Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only — no individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
