Need some earlier drops but not sure what I could swap.

I have another Jace, Memory Adept and Mind Grind on the way that I will sub for the 2 Ratchet Bomb unless a better suggestion is made.

Appreciate any advice.

If you just want to do something stupid, play whip.

I'm also inclined to believe that Dissolve is something you want.

I have a playset of Dissolve that used to be in the sideboard. I may put them back in, the scry and counter of ANY spell is nice, but the 3 CMC kinda turns me off it. It and Psychic Strike are jockeying for the spot in the deck, with Strike winning by a hair. Lately it's been more beneficial to mill the 2 than scry 1 in my meta. I can deal with a bad draw when I mill something crucial, which is pretty often.

I also have just one Whip of Erebos . Putting it in might be a little superfluous, since my big creatures that swing usually get through and end the game anyway, but I can throw it in on here and playtest it. Would be good for putting me out of reach just by blocking.
