Midrange Elves

WIP-ish. The deck has been working great but needs some optimizations.
Shakedown or Levitate instead of Sabotage are good options.
Don't be afraid of using Ashara, Ruthless Assassin effect, the deck has enough card draw and gas to feed her, especially with Tavia, Lethrai Raidleader tokens on midgame. Shadowlands Borderscout is another disposable unit. After one or two hits he already paid his cost, depending on which buffs you got for him. He can be discarded with Master Cartographer for use with Haunting Scream and previous combos.
All in all the deck has many lines to play with and is harder than it looks, would be too extensive to write every micro-interaction.

As a side note, you can (and I do sometimes) run a relic of your choice by replacing something, Sabotage is probably the easiest card to replace, or you can replace one of the Market cards for one relic, Dizo's Office is my recommendation. Even if Office is a really good value card, the other 4 cards are kind of a must in the market. Secret Passage or Lethrai Hideaway are probably the best bets for relics, although, Hideaway isn't a very great card by itself, and since this deck doesn't run out of gas easily, you will rarely find yourself in a position where you want to pay for it's effect and lose tempo. As for Secret Passage, even though the card has more uses with units with Infiltrate, it's pretty good with Ashara since the unit will die anyway, and it also helps to set up lethal. Both very optional cards, in any case.
