What it does
Creatures your opponents control have base power and toughness 0/1 until end of turn.
Rulings
2 official rulings, in the order Wizards published them.
- 2023-10-13
Flatline affects only creatures your opponents control at the time it resolves. Creatures they begin to control later in the turn won't change power and toughness.
- 2023-10-13
Flatline overwrites any effects that set a creature's power and toughness. Any existing effects or counters that raise, lower, or switch a creature's power and/or toughness continue to apply to the creature's newly-set power and toughness.
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.
