Mirror, Mirror
This is a nicely done deck I have tested on Apprentice. The theme of it is: The COPs and the Inviolability/Entangler/Wall combo are made to put out a monopoly on damage done to yourself - the only damage dealt to you should be your own - your mana burn. Get out the Mirror Universes, mana burn yourself during your upkeep, switch with opponent, win! For those who doubt this ability, or are playing that you can't mana burn yourself whenever you want (i.e. mana burn at end of turn) just burn yourself down to 3, play Avatar of Hope, switch, play Blessed Wind, kick their collective gluteals! ;)
