Field Contact seems like a great minion to build a Miracle deck around, and considering how many cheap Battlecry and Combo minions there are (that either replace themselves--Swashburglar, Wand Thief, Wandmaker--or deal damage--Pen Flinger, Prize Plunderer, Fogsail Freebooter) it's pretty simple to fill a deck with 1- or 2-Cost minions that become cantrips with Field Contact in play. Pen Flinger in particular seems like it might be too good in combination with Field Contact since you can keep casting spells to bring it back to hand then play it again to draw more cards.

My guess is that there will be a lot of different takes on Contact Miracles in the coming days and weeks. My version goes for a top-end of Mankrik because we can dig through the deck to find his wife very quickly with all our card draw, and Kazakus, Golem Shaper as late game minion generation. My guess is that there will be a lot of Rogues running Oil Rig Ambusher in place of those two, but I at least want to try out something that appealed more to my sensibilities.
