Improving my Harpie Deck

Hi,

I've been visting my local shop to play games against other people and made a Harpie deck because I think it's a fun off-meta archetype and has gotten pretty cool support card over the years. Unfortunately as someone who is pretty green when it comes to making functional decks I've tried my hand at making a first prototype that has been doing 'okay' at a local table, but it's very much struggling to project a lot of presence out of the first turn without just using Harpie's Feather Storm to lock the opponent out of their own turn.

I've recreated my current deck using the deckbuilder, and marked it as unlisted so I hope the link below works as intended:

Any advice on splashing in cards for an engine (if you can add a few words on how or why to use them would be very much appreciated as well), as well as some cards that would do well as sidedeck options (and what would be best to swap out for them in most situations), would go a long way in helping me improve my deck and my way of play.
