Flatline
From Doctor Who set
Flatline
Instant
Creatures your opponents control have base power and toughness 0/1 until end of turn.
Rulings
- 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.
- 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.
