An interesting deck, but based on what I'm seeing you have 13 creatures with which to win the game.
If you are trying to out-tempo your opponent (cards like Remand and Delver suggest that you are) you need to be able to lay a threat and ride it to victory while answering relevant threats/answers that your opponent presents. This indicates a model that needs to win in the early to mid game which, to me at least, means you need to be able to consistently represent a clock.
In short, I think you need more threats.
You have 10 counterspells and 12 removal spells (if you consider Thoughsieze to be removal), these are supposed to support your creature base, maybe drop a couple and add something like Bitterblossom or Tarmo (if you have) to the list to give it a higher threat density.
