This is my interpretation.
If it's your turn, during your upkeep you have 1 card in your library, you draw for turn = 0 cards in library at this point you use an ability or card in your hand that causes you to effectively draw a card, which you don't have, means that you automatically lose?
Impulsive draw: red gets to draw cards (technically, it exiles them) but only has access to cast them for the rest of the turn. The cards that are not cast remain lost in exile. R&D sometimes refers to this as the "Elkin ability"
120.4. A player who attempts to draw a card from a library with no cards in it loses the game the next time a player would receive priority.
104.3c If a player is required to draw more cards than are left in his or her library, he or she draws the remaining cards, and then loses the game the next time a player would receive priority.
120.5. If an effect moves cards from a player’s library to that player’s hand without using the word “draw,” the player has not drawn those cards. This makes a difference for abilities that trigger on drawing cards and effects that replace card draws, as well as if the player’s library is empty.
120.6. Some effects replace card draws.120.6a An effect that replaces a card draw
is applied even if no cards could be drawn because there are no cards in the affected player’s library.
120.6b If an effect replaces a draw within a sequence of card draws, the replacement effect is completed before resuming the sequence.
120.6c Some effects perform additional actions on a card after it’s drawn. If the draw is replaced, the additional action is not performed on any cards that are drawn as a result of that replacement effect or any subsequent replacement effects.
704.5b If a player attempted to draw a card from a library with no cards in it since the last time state-based actions were checked, he or she loses the game.
