Lluwen enters prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.)
Exile a creature card from your graveyard: Lluwen becomes prepared. Activate only as a sorcery.
Create a 1/1 black and green Pest creature token with "Whenever this token attacks, you gain 1 life."
Lluwen is a token engine: cast the Pest Friend copy whenever she's prepared to make a lifegain-on-attack Pest, then re-prepare her each turn by exiling creature cards from your graveyard. You flood the board with disposable bodies, fuel an aristocrats or go-wide engine off them, and grind value while gaining incremental life. Fill the yard early, then turn it into a steady stream of fodder that converts into damage, drain, or card advantage.
Add token doublers (Parallel Lives, Anointed Procession, Mondrak) and free sacrifice outlets (Ashnod's Altar, Viscera Seer, Carrion Feeder) to accelerate the loop. Layer in self-mill (Stitcher's Supplier, Grisly Salvage) so the graveyard never runs dry, and finish with aristocrats payoffs (Bastion of Remembrance, Bloodthrone Vampire) plus Skullclamp for card draw off dying Pests. For higher power, lean into a Pitiless Plunderer + sacrifice + recursion mana loop to chain multiple Pest casts per turn.
