The sideboard could use a little tuning, but the 3 Shape Anew + 2 Blightsteels is a great way to throw your opponent off and really put the heat on. Alternatively, running the Wing Splicers with Tempered Steel over the Blightsteels and Shape Anews is extremely helpful against decks with tons of flying.
My first deck list upload (also the only deck I have built IRL). Please comment!
