Lellecae, Goddess of History

Worship (When this creature enters the battlefield,
each opponent may have you gain control of a creature
they control of their choice. If they do, they create a
token that's a copy of this creature, except it's not legendary and it doesn't have indestructible.)
Indestructible
Whenever you cast an instant or sorcery, you may splice another instant or sorcery card onto it. If
you do, exile the cast card and the card that was spliced from your graveyard.
