Realize Your Potential deck built for the current Expedition meta. Support cards include: Backlash to counter the many control spells currently in play, Ice Bolt because Aegis is everywhere, Auric Condemnation to punish Gemblazer aggro and Steyer's Eyes to lock the void for Shadow decks. Outside of those cards, our strategy is to play Realize Your Potential on either Auric Sentry, Yojimba or Momentum Builder. Even if you don't draw Realize Your Potential, a Momentum Builder buffed by Alchemy Student can easily carry the game if you protect it.
Another option you can try adding is Nostrix, Grand Seer but it's a cost 6 and doesn't fit nicely into our power curve so I left it out. The deck plays well enough as it stands.
