Some creatures to consider to give you a better early game:

Picklock Prankster - Can be played to dig for more cards at instant speed (faeries or instant spells), and is a cheap creature to play.

Hypnotic Sprite - Option to play as counter and play as creature makes it a useful card. Not high power, but playable.

Spellstutter Sprite - Probably one of the best faeries you can play as it is a cheap flash creature that serves as counter magic.

Faerie Miscreant - A decent one drop option. Only really useful to give you early board presence that helps with Spellstuter Sprite, but also chance to give you card draw if you can open with more then 1 copy.

If you can afford:

Brazen Borrower - One of the best aggressive creature options you have that also serves as early bounce. Understable that it is hard to obtain due to cost ($$$), but if you can use them I would definetly say this would be a must for this kind of deck.

Cards I would remove:

Wasp Lancer - To slow and over costed

Glen Elendra Liege - Not enough multi colored creatures to take proper advantage of its bonus.

Cards I would trim copies:

High Fae Trickster - Would only run up to 2 copies due to high mana value of card. Personally would not use.

Faerie Swarm - overcosted if you don't have creatures on board, if you have creatures you might already be winning due to flying aggro. Maybe 1 or 2 copies in deck.

Oona, Queen of the Fae - Very late game card in a deck that doesn't really have a way to build to late game, seems like bad fit for this deck. Would only use it as a one of fun of, but ultimately cut.

Lastly I would suggest maybe some cheaper bounce spells like Fading Hope so it is easier to do something like bounce a threat and counterspell it on its way back to the board. Fading hope adds extra bonus to get some scry action and even can be used on own creatures as a form of protection.
