than distortion strike is definitely the better choice because it gives you the pump and you can target a different creature the next turn if needed. Scrying 1 isnt that much of a plus in this case. The 2 extra poison damage over the two turns is 20% of the winning damage

Replace aqueous form with distortion strike. costs the same and gives your guy a +1/+0 pump instead of the scry. Enchanting the creature ins't that crucial if you are trying to close the game out by turn 4 or 5
Elixir will shuffle them back in anyway
