With that said, I am more inclined to -4stifle for 2 chain/2pierce
Also, i think 2 cruise should be enough.
Stifle is great with Young Pyromancer.

I don't know which deck you play that you think all mana is used on cantrips all the time. Once you have a YP in play you can keep up mana.

Grixis Tempo lists usually played Delver, Dark Confidant, Young Pyromancer, Daze, Stifle, FoW, Probe, Ponder, Brainstorm, Lightning Bolt..

Not sure if I really love Monestary Swiftspear. The card goads you into playing spells on your turn when you otherwise would not do it.
