I'm having trouble figuring out whether the non-creature back side of an MDFC whose front side is a creature with power 2 or less could be put into the battlefield when alesha, who smiles at death triggers.
My guess is that this does not work because Alesha does not tell you to "cast" that card, which is when the modal decision would be made, but I am unsure of how the rules work for Alesha's "return target creature card."
If the card returning to the battlefield is a modal double-faced card, it must enter with its front face up (C.R. 712.10).
Remember that in general, you can choose between a modal double-faced card's front or back face only at the moment you're playing or casting that card (C.R. 712.7, 712.8), and not when you're moving it from one zone to another for any other reason.
The card that I was thinking of is valkmira, protector's shield.
