Essence Scatter should not cost 1 less AND let you Scry.
Remove Soul and Essence Scatter are both not played as a result.
That is incorrect. SCG's Deck Search engine tells me that 13 Standard decks with notable Top 8 finishes in their deck database over the last few months have some copies of Essence Scatter, including LSV's winning deck at the LA 5K.
And I'm hoping that your smiley next to the suggestion that Scry could somehow be justified by flavor is an admission of how utterly ridiculous that notion is. It's totally obvious that it's there for mechanical purposes; you don't need to hide that. It just needs some justification-- like if Scry were a major mechanic for the set, you could tack it on to things like they did in Fifth Dawn. Lose Hope, Magma Jet, and the like didn't bother explaining Scry with flavor, they just were. Scry is a great mechanic and I'm all for seeing more of it, but it seems pretty arbitrary to throw it on a card that's already strictly better than a Core Set staple.
Edit: And somehow this became even more bizarre while I was typing! Tribal Wizard? Mythic Rare? I'd be more amused if I didn't think you were serious.
