New takes on Ravnica classics like Guildmages and split cards await
A lot of commanders that have extremely powerful effects but are very costly like Narset, Enlightened Master and Ramos, Dragon Engine go here
Basic lands, Foreign, or silver/gold bordered cards
Where it gets truly strong, though, is playing those creatures that get arbitrarily large think Malignus, or Taurean Mauler and following up with instant speed Burn spells
Caesar, Marneus Calgar, Jetmir, Baylen, and Chatterfang introduce different token abilities and mechanics for effective gameplay
Similarly, if another effect allows you to cast a creature spell from your graveyard, you may use that permission and later use The Tomb of Aclazotz's ability to cast another creature spell
