Just be aware that the deck uses Hidden Objects (new 2 mana Spell that discovers a secret) as a spell school generator. There are 5 secrets in Standard and 3 have different spell schools so be mindful of that when making the choice.
It’s the only deck Khadgar can be played in and I won’t lie he is “useful”. You just drop him and let him do his thing. Other than that, regular Sif Mage:)
