Does Darius's +2 effect trigger on defense and/or offense, specifically if playing spells as the second card in a showdown or when using defensive spells on the opponent's turn?

Question

Accepted Answer

Ruling: Darius's +2 effect triggers after the second card is played (resolved) in any turn, including both your turn and your opponent's turn.

Sequence:
- Play first card in a turn
- Play second card in a turn
- Darius gains +2 after the second card resolves

Nuances:
- Works on both offense (your turn) and defense (opponent's turn)
- Can be triggered with actions/reactions played during opponent's turn
- Does not require energy if playing cards from hidden (e.g., controlling two fields with hidden cards)
