If I'm the attacker and play a spell during my focus, after that spell resolves and I pass, does my opponent play nothing, do I get another focus since I played a card on my first focus?

Ruling: No, you do not get another focus. After a non-initial chain resolves, focus moves automatically to the next player.

Sequence:

• Attacker plays a spell during their focus
• Spell resolves (non-initial chain)
• Focus automatically moves to the defender
• If both players pass focus with no chain being started, focus continues to alternate

Nuances:

• The rule about gaining focus after playing a card only applies to the Initial Chain (When I Attack and When I Defend triggers)
• After non-initial chains resolve, you don't pass focus - it moves automatically to the next player
