The final pages of the experiment log were blank. Investigators found it abandoned on a desk in the researcher's lab, open, the pages flipping in the wind from a shattered window.

"Metamorphosis is a process."
—Laboratory notes

Flying

Shadows over Innistrad

Flying
At the beginning of your upkeep, put the top card of your library into your graveyard. If it's an instant or sorcery card, transform Aberrant Researcher.

If a replacement effect causes the top card of your library to go to a zone other than your graveyard, Aberrant Researcher will still transform if that card was an instant or sorcery card.

No player may take any action between the two steps of Aberrant Researcher's triggered ability. If the card put into your graveyard is an instant or sorcery card, Aberrant Researcher will have transformed before a player can take any action.
