As long as there are four or more lore counters among Sagas you control, Tom Bombadil has hexproof and indestructible. Whenever the final chapter ability of a Saga you control resolves, reveal cards from the top of your library until you reveal a Saga card. Put that card onto the battlefield and the rest on the bottom of your library in a random order. This ability triggers only once each turn.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.) I — Destroy target nonland permanent an opponent controls. II — Search your library for a Forest card, put it onto the battlefield tapped, then shuffle. III — Creatures you control gain deathtouch until end of turn.
