Can you draw a card from Warrens and Merchant effects if you have an empty hand and cannot discard?

Ruling: Yes, you can draw even if you discard 0 cards. The draw effect is not conditional on successfully discarding.

Nuances:

• If the draw were conditional on the discard, the card would use "if you do" clause or "discard to draw" syntax
• The game uses "discard, then draw" syntax when effects are not conditional
• Conditional effects in Riftbound use different templating (e.g., "discard 1 to return" or "if you do" clauses)
