Sam, Dungeon Master

If Sam, Dungeon Master is in your command zone, its static abilities are active as if he was on the battlefield.

You may cast Sagas from your hand without paying their mana costs. Whenever the final chapter ability of a Saga you control resolves, remove all lore counters from it instead of sacrificing it. Whenever a Saga you control leaves the battlefield, gain life equal to its mana cost.

Creatures you control are legendary.
