Is this the new split card format for Amonkhet? It has been leaked in the last couple of days and looks like it may be legitimate. If so what are you thoughts?
Dusk - 2ww
Destroy all creatures with power greater or equal to 3
Dawn - 3ww
Consequence - Cast this spell only from your graveyard, then exile it.
Return all creature cards with power less than or equal to 2 from your graveyard to your hand.
The design of the card maybe so that when it goes to the graveyard you can place it on its side so that the graveyard cast is still visible.
