If my opponent uses Arcane Shift to banish their only unit at the Battlefield and plays it to Base during combat, does Draven Legend's ability trigger to draw a card for winning combat?

Ruling: Yes, you draw a card. Combat does not end immediately when one player has no units at the Battlefield. Draven Legend checks at the end of combat, and if the opponent's unit was moved to Base, you have won that combat.

Sequence:

• Opponent uses Arcane Shift to banish their unit from Battlefield
• Opponent plays the banished unit to Base (or another location)
• Both players pass with focus on an empty chain
• Combat ends
• Draven Legend checks and sees you won the combat, triggering the draw

Nuances:

• Combat continues until both players pass with focus on an empty chain, not when units leave the Battlefield
• The opponent retains control of the Battlefield until the end of combat even after their unit is banished
• If the opponent played the unit back to the same Battlefield, you would not win the combat
