What happens if a non-double-faced card is instructed to transform?

When a non-double-faced card is instructed to transform, the outcome is that nothing happens. Transformation is a game mechanic specifically designed for double-faced cards, which have a front and a back side. If a card that is not designed to transform is instructed to do so, the rules dictate that the instruction has no effect.

The reason for this is that transformation requires a specific type of card printed with the double-faced mechanic, which includes a transformation instruction on the card. Since non-double-faced cards lack this characteristic, they cannot undergo any transformation, and thus no action occurs as a result of this instruction. This aligns with the comprehensive rules of Magic: The Gathering, which specify that if a card cannot transform for any reason, including not being double-faced, the action simply resolves without effect.
