2 Thought Lash
The deck is a cute thought experiment. My first Legacy deck was Oops, All Spells!, and I immediately took a liking to Thassa's Oracle. I have a casual version of this that doesn't use the high-end cards in the deck, but instead utilizes Mana Severance, Selective Memory, and Boomerang. Unsure if Leveler belongs in the "real" version of this, or if I should just run 2 each of Severance and Selective. I don't actually have a proper means of testing this as I sold basically all of my Legacy collection recently, but I'm curious as to what people's thoughts are on something like this. What could change? What could make the deck better? Do we want Fetches? And so forth.
Maybe drop Levelers and Preordains for a playset of Severance and Selective?
