1. Hall of Oaths
Hall of Oaths is a Legendary Land that allows you to bring back enchantments from your graveyard to your hand. I think this would be a good card if it is real.
2. Elspeth Ascended
This Elspeth can give protection or put a 6/6 with flying, lifelink, and protection from all colors. I think that she is a game winner.
3. Elspeth, Paladin for Good
This Elspeth is slightly different. She can put powerful tokens onto the battlefield or get you a mighty Emblem that will destroy all other non-land permanents. She is sure to be a game winner.
