Relis, traitorous Archmage

Delve
At the beginning of your upkeep, create a clue
token. You may mill a card instead of paying the
activation cost of clue token.
When Relis, traitorous Archmage enters the Battlefield, if it was cast from your graveyard,
shuffle your graveyard into your library.
Whenever you have less than 10 cards in your library, you loose the game.
