Mirror-Sigil Sergeant and Infinite Reflection have both had my attention to build a deck around for quite some time. I never thought to put them in the same deck until recently however, and the result has worked rather well actually.
The goal of this deck is: Plan A) Wall up early on and use Mystic Specualtion and Brainstorm to hit land drops consistently and gather a Mirror-Sigil Sergeant, Frost Titan, and/or Infinite Reflection from the deck. As soon as you can get a Mirror-Sigil Sergeant or Frost Titan to stick for a turn, play Infinite Reflection. The result is devastating, as all your previously innate walls become scary killing machines. If you can't get a titan or sergeant to stick just slam the reflection on your enemy's scariest creature and go to town. Plan B) Keep the Walls up and protect the first Mirror-Sigil Sergeant that sticks for at least a turn or two. After that, short of a board wipe they will quickly multiply into out-of-control proportions. When you have enough copies, run em' over with all that trample-y goodness.
