Contagious Vorrac is a great way to impact the board while keepping the land drops coming.

Planar Disruption is a straight better Pacisfism.

Barbed Batterfist is a good way to push attacks/trades while keeping some power in the board.

Crescendo is good combat trick that provides card advantage

Fallaji Archaeologist: milling is nice. Being able to make a 1/4 for 2 mana is nice too.

Dwaven Forge-Chanter: great 2drop for prowess strategies

Recomission: cheap way to reanimate a value creature + extra counter synergie

Gixian: great payoff for aristocrats. lili specter was never that good in cube

Go for the Throat: great range to a cmc2 removal

Overwhelming Remorse: cool removal that exiles. Shines the most in mill/sacrifice decks, but is going to be a 3 mana removal in a lot of other decks too
