Wizards revealed the five intro decks in today's Arcana from Wizards, along with it we get the name of five cards. This info has been largely previously identified by MTG Salvation forums, but it is interesting none-the-less.

Five cards we don't know what they do:

Student of Warfare

Surrakar Spellblade

Drana, Kalastria Bloodchief

Conquering Manticore

Gigantomancer
