Recommendation

-4 Meddling Mage
-1 Rafiq of the Many
-4 Elvish Spirit Guides

+4 Leyline of Sanctity
+1 Ponder
+1 Mystical Tutor
+1 Merchant Scroll
+1 Brainstorm

You aim for start of game with leyline, as it is impossible to stop and
deny a lot of nasty stuff you don't want to hit you with.
Mana isn't an issue for this deck, you need more blue spells
for pitching off to Force of Will.
