Activate Emry by tapping it, allowing you to cast Lotus Petal from your graveyard.
Cast Lotus Petal by paying 0.
Displacer Kitten triggers, blinking Emry.
When Emry enters, it triggers, causing you to mill four cards.
Activate Lotus Petal by tapping and sacrificing it.
Repeat.
This clever loop relies on Displacer Kitten's avoidance trigger to repeatedly reset Emry, Lurker of the Loch every time you cast a noncreature spell. By tapping Emry to cast Lotus Petal straight from your graveyard, you trigger the Kitten to blink Emry; as Emry re-enters the battlefield, she mills four more cards to fuel your options. Sacrificing that same Lotus Petal for mana ensures you have the resources to keep the chain going, while Temur Ascendancy sits comfortably on the board to grant your creatures haste and turn those incoming entries into a steady stream of drawn cards.
