Ryze, The Rune Mage

When Ryze enters the battlefield or at the start of your upkeep, return a Delve Into The Past from your graveyard to your library.

Attack: Search your library for a Delve Into The Past, put it on top of your library, and then shuffle.

When 3+ unique World Runes are on the battlefield grant Ryze +1/+1, hexproof, and the text: When Ryze attacks activate all your World Runes. If you attack with 5 unique World Runes on the battlefield, you win the game.
