If i play a card with sword 4 and i dont have 4 cards in discard and hand to cull and i only have 2 in discard.
i must cull as much as i can? Or i can cull only 1.
Step 2 of the cull action: "Then, select a number of cards in your hand and/or discard pile up to the Strength value of the card played."
Cull as many as you want between 0 and 4 in your example.
