I like the idea of the deck.
First, is there a reason why you play
Brainstorm over
Preordain? If you have cards in the next 2 cards of your library which you do not want to have at the moment
Brainstorm does not help you,
Preordain could.
For me it looks like the deck is a beat down deck -->
Aether Swooper is not a beat down card, he is more of a .... energie card (aka bad), is he your anti-delver with a buff card (
Mirran Mettle --> too good for that,
Bonesplitter --> he wil not attack,
Inventor's Goggles --> yea that is good ... a precise 2 card combo vs delver)? or does he generate an artifact (then he is a 2 mana 1/1 artifact)
Inventor's Goggles is so slow, it costs 1 mana and deals 1 damage a turn, and the opponent can play around it (no instant like
Mirran Mettle)
In my opinion
Aether Swooper should be replaced by .. like
Frogmite (still 15 creatures,
Inventor's Goggles replaced by ...
Thoughtcast or
Chromatic StarI like the Snow-Covered Lands /
Evolving Wilds /
Arcum's Astrolabe combi package,
but right now it seems weaker than the Artifact lands /
Prophetic Prism and
Chromatic Star package
I just
fear that you will run in the problem that you lack artifacts by turn 2/3
