What happens when a DFC card copies another DFC card and transforms?
Asked by TakeInventory 9 months ago
What happens? Does it transform or not? If it does, what creature does it become? Or does it do a weird thing like transforming from Delver into the same Delver because the card is still a copy?
Heir (or whatever it is) would still transform.
"711.5. Only permanents represented by double-faced cards can transform. (See rule 701.26, "Transform.") If a spell or ability instructs a player to transform any permanent that isn't represented by a double-faced card, nothing happens.
Example: A Clone enters the battlefield as a copy of Wildblood Pack (the back face of a double-faced card). The Clone will be a copy of the Wildblood Pack. Because the Clone is itself not a double-faced card, it can't transform."
Because double facedness is not a copiable characteristic, by definition it is not overwritten by copy effects. Therefore the card would be a Delver of Secrets with a transform trigger on the stack. It would transform into Heir to the Night Flip.

Example: A player casts Cytoshape, causing a Kruin Outlaw (the front face of a double-faced card) to become a copy of Elite Vanguard (a 2/1 Human Soldier creature) until end of turn. The player then casts Moonmist, which reads, in part, "Transform all Humans." Because the copy of Elite Vanguard is a double-faced card, it will transform. The resulting permanent will have its back face up, but it will still be a copy of Elite Vanguard that turn.

In the system of layers that the game uses to determine a card's characteristics, the printed text of a card is basically "Layer 0" and copy effects are in Layer 1. In your example the copy effect turning Heir of Falkenrath into a Delver is still going to be applied on top of Heir to the Night Flip's printed characteristics. It will go back to being Heir to the Night when the copy effect finally wears off.

Importantly, Heir to the Night Flip is a Delver of Secrets Flip in this scenario, it is not an Insectile Aberration even though it's back face is up and it transformed while being a copy. Interestingly, if you activated Heir of Falkenrath and your opponent responded by casting Cytoshape both targeting and choosing Heir of Falkenrath (so that it became a copy of itself) it would transform (so Heir to the Night Flip was face up) but still be an Heir of Falkenrath.
