When Kayn moves for the second time to a battlefield from a battlefield and doesn't kill the defending units, does he recall back to base or back to the field he attacked from?

Ruling: Kayn recalls back to base. Recalling always means return to base.

Sequence:

• Kayn moves for the second time from battlefield to battlefield
• Kayn fights but doesn't kill the defending units
• Combat ends in a tie
• Kayn (the attacker) gets recalled to base

Nuances:

• If the defender passes the turn after this recall, they get the point for holding the battlefield
