Rulings
5 official rulings, in the order Wizards published them.
- 2024-11-08
If Mossborn Hydra somehow enters at the same time as one or more other lands you control, its last ability triggers for each of those lands.
- 2024-11-08
A landfall ability doesn't trigger if a permanent already on the battlefield becomes a land.
- 2024-11-08
To double the number of +1/+1 counters on Mossborn Hydra, put a number of +1/+1 counters on it equal to the number it already has. Other cards that interact with putting counters on it will interact with this effect accordingly.
- 2024-11-08
Whenever a land you control enters, each landfall ability of the permanents you control will trigger. You can put them on the stack in any order. The last ability you put on the stack will be the first one to resolve (As a result, you can have those abilities resolve in the order of your choosing.).
- 2024-11-08
A landfall ability triggers whenever a land you control enters for any reason. It triggers whenever you play a land, as well as whenever a spell or ability puts a land onto the battlefield under your control.
Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.

Prices from Scryfall, which tracks the TCGplayer and Cardmarket markets. They move daily and are a guide rather than a quote. Search TCGplayer for Mossborn Hydra. It runs a name search across every version, which covers the printings TCGplayer publishes no direct link to.
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.
