5 rulings from Wizards of the Coast
- 1 September 2023If the creature loses flying before Shadow Puppeteers's last ability resolves, the creature will still become a red Dragon with base power and toughness 4/4 in addition to its other colors and types until end of turn. It won't gain flying.
- 1 September 2023If the creature stops being a creature before Shadow Puppeteers's last ability resolves, it will become red until end of turn in addition to its other colors. Since it's not a creature, it won't gain the Dragon subtype, and it won't have base power and toughness 4/4.
- 1 September 2023Shadow Puppeteers's last ability overwrites any previous effects that set the creature's power and/or toughness to specific values. Any power- or toughness-setting effects that start to apply after Shadow Puppeteers's last ability resolves will overwrite this effect.
- 1 September 2023Shadow Puppeteers's last ability doesn't remove any abilities the creature has.
- 1 September 2023Effects that modify a creature's power and/or toughness, such as the one created by Squeak By or a +1/+1 counter, will apply to the creature no matter when they started to take effect.
