Rhastakhan Freeze Mage

This new iteration of freeze/exodia mage uses Splitting Image along with Arcanologist and Ice Barrier for a more consistent early game. Almost every minion in this deck gives insane value if copied by splitting image. You can even pull of your infinite damage combo early if the splitting image goes off on an apprentice or Antonidas.

Use Simulacrum to obtain copies of Sorcerer's Apprentice, then discount them with Leyline Manipulator. Summon two 0-cost apprentices along with Archmage Antonidas and either a 2-cost apprentice or a Molten Reflection to get infinite fireballs for 10 mana!
