(1/6) Elana seems like a high roll deck, but even if you don't have elana on turn 4/5 you have the tools to survive until you draw her. Run olivia and hold out as long as you can while spamming zoe healing and praying to god.
(2/6) De la fille is incredibly important to this deck. If you don't draw her you'll usually lose against 90% of the meta. Artifact, technolord, mirror, etc. Because of this I like to keep her during the mulligan phase so she doesn't get lost in the bottom half of my deck.
(3/6) Aegis alt wincon is fake news. 90% of the time you won't even get it in your hand, and 90% of the times you do you won't be ahead enough to play it. I basically use limonia only for cost reduction and olivia synergy. Don't forgo better plays just to try and get aegis down.
