Gandalf, the Grey

When Gandalf, the Grey enters the battlefield for
the first time, create a 'There and Back Again'
emblem.
Whenever Gandalf, the Grey attacks, you may
search the top 5 cards of your library for a
Cleric, Rogue, Warrior or Wizard card. Reveal it
and put it into your hand, and the rest in the
bottom of your library.
Evoke {1}{g}{u} Evoking will only contribute {1} to Gandalf's commander tax.
