Altar of Tellers

If a Saga you control with a number of chapters
higher than 0 would be put into a graveyard
when it has a number of lore counters on it
higher than or equal to the number of chapters
it has, exile it instead. If you do, return it to the
battlefield at the beginning of the next end step.
In the midst of the forest, there's a spot where old
heroes come to retire their weapons and tell their
stories - and newer ones come to hear those stories
and earn their weapons.
