Sphinx's Tutelage and Day's Undoing

Newish to mtgpq, 
why doesn't Day's Undoing trigger Sphinx's Tutelage? Is the "draw 5 cards" from it any different from the Pull from Tomorrow's "draw 5 cards"? 

Thanks

    It does. 

    But mtgpq is assymetrical. 

    Meaning you will always draw before opponent does. 

    Your opponent's hand is empty when you're drawing, meaning the sphinx triggers on no targets and fizzles. 

    Note that when opponent sphinx day undoing combos on you, your first card will always be hit by it because like I said, you always draw before opponents.

    Indeed, Day's Undoing states "Both players...". This is solved in paper magic via rule 101.4, for example namely "If multiple players would make choices and/or take actions at the same time, the active player (the player whose turn it is) makes any choices required, then the next player in turn order".
    - In the context of Day's Undoing paper magic, the players draw simultaneously so only triggered effects are put onto the stack in this order. In MTGPQ each singular card drawn triggers and resolves the effect instead of putting the effects onto the stack to be resolved afterwards.
    In fact I found an example explained really nicely specifically of this combination in paper magic:

    Here is what happens when the active player casts Day's Undoing:

    1. The active player shuffles his or her hand and graveyard into his or her library and then draws seven cards.
    2. Sphinx's Tutelage triggers seven times, but those triggers do not go on the stack just yet.
    3. The nonactive player shuffles his or her library hand and graveyard into his or her library and then draws seven cards.
    4. The turn ends.

    However, If the spirit of the rule were implemented in MTGPQ too, it would solve the problem of symmetry.
    In a triggered (event)-based environment, it usually helps to use context information such as "ActivePlayer" and "InactivePlayer", but I am clueless on the implementation behind-the-scenes, so I wouldn't know how complicated such a change is.
    Also with Amonkhet it was mentioned that some sort of stack was implemented in MTGPQ, so I guess this could allow the team to revisit old cards to "adapt" them for the sake of symmetry :smile:
