The Sphinx isn’t triggered by the second card drawn by Folio.
Do I win the First Bug in Eldraine prize??
sigh I assume this is a similar bug to the longstanding Alhammaret’s Archive bug.
@Tombstone @Oktagon_Support alert the team.
(and this is not the first Eldraine bug reported, sadly)
Thanks for the response.
Update: Ditto Folio/Jessian Thief. Jace is sad 
@Oktagon_Support - this is still an issue. I observed it today in Titanomanchy.
My combo consisted of Folio of fancies, underrealm lich and devourer of memory.
The UL is supposed to destroy 3 cards each time I draw a card and Fof should double the card drawn on the start of my turn, so DoM should grow with 6 at the start of my turns.
However, DoM only grows with 3, so UL and DoM works correctly, leading to the conclusion that the 2nd card drawn with Fof is actually not drawn.
Hi @Tremayne
Thank you for the heads up!
This issue is now under investigation.
