Ideally:
Upgrade Boneshards for Bitter Triumph
Add some Traverse the Ulvenwald
Vanishing Verse is potentially a good removal spell
Thoughtseize is pretty great for using on yourself

Macabre Waltz - could be interesting if you need more ways to discard cards

Maybe Unearth is better (and cheaper) than Can't Stay Away
