Lots of early options to grant face Aegis and interfere with Hunt decks, as well as prevent Shadow discards.
Heavy Hail is in the deck, rather than market, so we can play it early when it matters against aggro. If aggro decks become less common consider moving it to market.
You can run more copies of Signing Bonus, I only have two because I am cursed to draw all of them in my opening hand if I run more.
Don't play Deep Freeze against any decks with Fire and Time. It's virtually guaranteed they have Exodus. If you are facing lots of Creation decks then you can probably take Deep Freeze out of the market and put in something else.
