Mightform Harmonizer Rulings
- Jul 25, 2025 If a creature’s power is less than 0 when it’s doubled, instead that creature gets -X/-0, where X is how much less than 0 its power is. For example, if an effect has given Bear Cub, a 2/2 creature, -4/-0 so that it’s a -2/2 creature, doubling its power and toughness gives it -2/+2, and it becomes a -4/4 creature.
- Jul 25, 2025 If an effect instructs you to “double” a creature’s power, that creature gets +X/+0, where X is its power as that effect begins to apply. Similarly, a creature whose toughness is doubled gets +0/+X, where X is its toughness as the effect begins to apply.
