What it does
Flying
When this creature enters, you may discard any number of cards. When you do, up to that many target creatures each get -2/-2 until end of turn.
Rulings
One official ruling, as Wizards published it.
- 2024-09-20
You don't choose targets for Miasma Demon's last ability at the time it triggers. Rather, a second "reflexive" ability triggers when you discard cards this way. You choose targets for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.
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 Miasma Demon. 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.
