: (As this saga enters and after your draw step, add a lore counter. Sacrifice after I.)

I: Target opponent discards a card if they control a legendary permanent.

II: Target creature you control becomes a copy of another creature on the battlefield until end of turn.

III: Exile a nonland card from target opponent's graveyard. For as long as it's exiled, you may cast it, and spend mana as though it were mana of any color to cast it.
