If you're taking about this list, http://sales.starcitygames.com//deck...p?DeckID=90582 , here's what i would do against regular miracles:
-4 Daze
-1 Forked Bolt
-2 Lightning Bolt
-1 Spell Pierce
+3 Pyroblast
+3 Therapy
+1 Needle
+1 Clique
I really don't like daze in this matchup because they just play around it and it becomes pretty useless after turn 2/3. I like to keep a few bolts in because miracles tend to bring in mentor post-board, and worst-case scenario, they can just kill a random clique or snapcaster. Spell pierce is fine but probably worse than the cards you're bringing in. As for mentor miracles, I would do more or less the same thing. Maybe you would bring in the singleton staticaster.
