Can Divine Judgment be cast even if the opponent doesn't have 2 cards in hand or any gear?

Ruling: Yes, Divine Judgment can be cast regardless of whether your opponent has 2 cards in hand or any gear. The choices are made on resolution and it doesn't target anything, so there are no requirements for what players must have when casting it.

Sequence:

• Divine Judgment is cast (no requirements needed)
• On resolution, choices are made
• Each player chooses units and gear (they don't have to control them)
• Players can choose the same units as each other
• Excess runes and cards in hand are recycled

Nuances:

• The units/gear chosen don't have to be ones controlled by the player making the choice - they can choose their opponent's units
• Players can choose the same units as each other (unlike King's Edict which has a clause preventing this)
• If you cast Divine Judgment with 4 units and your opponent has none, you keep those 4 units and they recycle their excess resources
