Whenever a non-token permanent is put into your graveyard, you may pay {e}. If you do, you may put a permanent from your graveyard onto the battlefield tapped under target opponent’s control.

Whenever that permanent leaves the battlefield, that permanent’s controller loses life equal to its mana value, you gain that much {e}, then exile that permanent instead of putting it anywhere else.

Whenever a player adds a lore counter to a Saga, you gain {e} and target player loses 1 life.
